Mittelman earned his in from and previously contributed to the while at the University of Texas Southwestern Medical Center, later serving as faculty at where he focused on applying computational methods to genomic data. His background in developing tools for analyzing complex biological datasets informed the company's inception. Mittelman's motivation for establishing Othram stemmed from recognized limitations in traditional , particularly the challenges posed by degraded or low-quantity samples common in cold cases, which often yielded insufficient profiles for identification. After two decades addressing medical challenges, he pivoted to forensics to bridge these gaps and enable resolutions for long-stalled investigations. Key leadership includes co-founder Kristen Mittelman, who serves as Chief Development Officer and oversees operational aspects, bringing her expertise in chemistry from a . David Mittelman remains the CEO, guiding strategic direction. The initial vision centered on creating a vertically integrated dedicated to forensic sequencing and , allowing Othram to handle the full pipeline from evidence processing to analysis in-house and support through proprietary tools like the DNASolves database, reducing dependence on external public resources.

Headquarters and operations

Othram is headquartered at 2829 Technology Forest Boulevard, Suite 100, in , a suburb north of , where it established its primary facilities in 2018. The company's operations center around specialized, accredited laboratories designed for , featuring high-throughput sequencing capabilities with equipment such as the Illumina NovaSeq 6000 to handle degraded or efficiently. As a private forensic laboratory, Othram collaborates exclusively with agencies on a case-by-case basis to generate investigative leads from biological evidence, without providing genetic testing services. Funding for its work derives from government grants, through the DNASolves platform—which enables public donations to specific cases—and private contributions, allowing the lab to prioritize unsolved violent crimes and unidentified remains. The operational workflow commences with submitting case details and via a secure online request system, which Othram reviews for feasibility before coordinating secure shipment to the lab for processing, including , library preparation, sequencing, and bioinformatics analysis. To build family trees for , the lab supplies at-home cheek swab kits to potential relatives, whose anonymized profiles are added to the private DNASolves database for matching. Othram maintains rigorous ethical standards in handling genetic data, complying with regulations through measures like data minimization, unidirectional workflows to prevent , and selective use of non-public databases for particularly sensitive investigations to safeguard third-party . Employing a multidisciplinary of 51 to 200 professionals, including geneticists, bioinformaticians, forensic analysts, and genealogists, Othram supports by processing hundreds of cases annually and has contributed to the resolution of thousands of cold cases worldwide, with over 600 publicly announced, as of November 2025.

Technology

DNA analysis methods

Traditional short tandem repeat () analysis, the standard method in forensic DNA testing for decades, faces significant limitations when dealing with degraded or low-quantity samples common in cold cases. STR profiling relies on amplifying longer DNA fragments (typically 100-500 base pairs), which often fail to yield complete profiles from environmentally exposed evidence like bones, , or historical remains, leading to inconclusive results or inability to perform . Othram addresses these challenges through advancements in tailored for forensics, enabling the generation of comprehensive DNA profiles from highly degraded samples that STR methods cannot process. Their approach shifts to sequencing (MPS) of shorter DNA fragments (as small as 50 base pairs), which are more likely to survive , thus expanding the pool of solvable cases. Central to Othram's methodology is Forensic-Grade Sequencing (FGGS®), a process that achieves high-coverage sequencing from minimal input, such as as little as 15 cells or 0.1 nanograms of . FGGS incorporates specialized , enrichment via targeted amplification, chemical repair of damaged molecules, and advanced error-correction algorithms in the bioinformatics pipeline to ensure accurate reconstruction of the despite or fragmentation. This end-to-end workflow, performed in an ANSI-accredited ISO/IEC 17025:2017 laboratory, digitizes the full spectrum of for downstream analysis. In SNP testing, Othram captures hundreds of thousands of single nucleotide polymorphisms (), such as approximately 650,000, across the , far surpassing the 20-30 markers in STR profiles. These dense SNP datasets enable precise estimation of ancestry and distant relatedness by identifying shared genetic segments, providing a robust foundation for in forensic contexts. Sample preparation at Othram emphasizes handling challenging evidence types, including touch DNA from surfaces, skeletal remains, and ancient artifacts, through unidirectional workflows to prevent contamination and maintain chain-of-custody. For instance, in a demonstration case involving bones discovered in 2016 but linked to a death in 1881, Othram extracted and sequenced DNA from the degraded remains, successfully generating a profile that facilitated identification via genetic genealogy.

Genetic genealogy techniques

Othram applies sequenced DNA data to investigative genetic genealogy by first generating single nucleotide polymorphism (SNP) profiles containing hundreds of thousands of markers from forensic samples, enabling the detection of distant relatives such as third- or fourth-degree cousins. These profiles are then uploaded to opt-in public databases like GEDmatch and FamilyTreeDNA, where users have consented to law enforcement matching, allowing Othram to identify genetic matches through proprietary KinSNP® analysis. Pedigrees are constructed using algorithms that perform cousin matching by measuring shared DNA segments in centimorgans (cM) and automatically clustering matches based on overlapping identity-by-descent (IBD) regions to infer family relationships. To enhance profile utility, Othram employs phasing and imputation techniques, which reconstruct haplotypes by inferring missing genotypes from reference panels of known ancestries, thereby narrowing potential relatives and improving match compatibility with databases. of matches follows, confirming biological links by verifying shared segments across multiple individuals, which helps distinguish true relatives from coincidental matches and builds reliable family trees. While imputation fills gaps in sparse data, Othram prioritizes directly observed SNPs from high-coverage sequencing to minimize errors, particularly in cases involving degraded or mixed samples. In 2025, Othram introduced SNPSuite, a secure, offline application designed for forensic laboratories to perform advanced SNP-based and comparisons without compromising . Othram's in-house team of genealogists collaborates on pedigree verification, cross-referencing genetic clusters with , vital statistics, and to trace lineages and identify candidates. This manual review integrates automated tools with traditional methods, such as analyzing files for relationship graphs, to resolve ambiguities and generate investigative leads for . Ethical protocols are integral to Othram's process, requiring explicit opt-in consent from database users for forensic searches, ensuring only profiles from consenting individuals are used for matching. Non-case data, including third-party reference profiles, is anonymized during analysis to protect , with results presented as hypothesis-testing frameworks rather than definitive identifications to uphold standards of genomic .

History and development

Establishment and early years

Othram was founded in 2018 by David Mittelman and Kristen Mittelman, drawing on their academic backgrounds in genomics from Baylor College of Medicine, where they had been developing advanced genomic techniques for analyzing degraded DNA samples. The company, headquartered in The Woodlands, Texas, initially concentrated on demonstrating the feasibility of its proprietary Forensic-Grade Genome Sequencing technology using historical samples, such as the successful identification of human remains dating back to 1881. This early work highlighted the potential of the method to handle extremely old and compromised evidence, setting the stage for forensic applications. In its formative phase, Othram faced significant challenges in refining its technology for low-quantity, degraded DNA while navigating limited funding available for forensic research and development. To overcome these hurdles, the company established initial partnerships with Texas law enforcement agencies, leveraging its proximity and expertise to test and validate its processes on real-world cases. These collaborations were crucial for building credibility and access to evidence, despite the field's traditional reliance on underfunded public labs. Breakthroughs emerged in 2019 when Othram assisted in the Christine Jessop murder investigation, where provided crime scene evidence for genetic analysis, leading to the eventual identification of the perpetrator through genealogical profiling. The company also began applying its methods to early unidentified remains cases, contributing to identifications that demonstrated the technology's reliability beyond standard DNA matching. Prior to 2020, Othram invested in constructing specialized laboratory infrastructure designed specifically for end-to-end forensic sequencing, including automated enrichment and unidirectional workflows to prevent . This expansion was supported by securing an initial $4 million Series A funding round in March 2019, which enabled scaling operations. Despite its for-profit structure, Othram adopted a mission-oriented approach akin to a non-profit, often subsidizing or funding cases to address funding gaps in investigations.

Expansion and milestones

During the early years of the in 2020 and 2021, Othram experienced significant growth in case submissions from agencies, driven by increased interest in advanced DNA technologies for cold cases amid disruptions to traditional investigative workflows. In , the company launched DNASolves, a platform that enables public contributions to fund forensic testing for unsolved cases, which gained traction during this period to support resource-limited agencies. Othram also forged key partnerships with federal entities, including the FBI's New York field office for victim identifications, and numerous state agencies to process evidence in high-profile investigations. A pivotal funding milestone came in September 2021, when Othram secured $18 million in Series B financing led by Gigafund, enabling expansion of its laboratory capacity and technology development to handle a broader range of forensic evidence. This investment supported subsequent initiatives, including the 2024 launch of Project 525, a targeted effort funded through donations to apply forensic-grade genome sequencing to 525 unidentified juvenile cases in the National Missing and Unidentified Persons System (NamUs), aiming to restore identities and advance related investigations. As of November 2025, Project 525 had resulted in at least nine identifications, contributing to Othram's estimated total of over 6,000 case resolutions since inception. By 2023, Othram's technologies had contributed to the resolution of over 1,500 cases annually, marking a substantial increase from earlier volumes in the dozens per year. From 2022 to 2025, Othram broadened its scope to include specialized work on and Murdered Persons (MMIP) cases through a 2025 partnership with the U.S. ' Missing and Murdered Unit under Operation Spirit Return, focusing on identifying remains and repatriating victims to tribal communities. The company also established international collaborations, such as with the Australian Federal Police's National DNA Program in 2022 for applications and with in to develop training tools for . Technological advancements during this period included the introduction of SNPSuite software in 2025 for deployable SNP analysis workflows and OthramOS, an AI-driven platform to accelerate evidence organization and kinship matching, reducing processing times for complex cases. Othram's overall quantitative growth reflected this expansion, with annual case resolutions scaling from limited numbers in 2020 to thousands by 2025, supported by over $48 million in total funding across multiple rounds. To foster ongoing innovation, the company established the Othram Fellowship Program, a paid 120-day initiative launched in 2024 to train researchers and law enforcement professionals in forensic genetic genealogy techniques.

Notable contributions

Identification of suspects in cold cases

Othram's approach to identifying suspects in cold cases relies on advanced to create detailed genetic profiles from collected at crime scenes, such as semen or from decades-old samples. These profiles are uploaded to genealogical databases to match with of potential perpetrators, after which and genealogists construct family trees to narrow down candidates. Confirmation occurs through direct DNA comparison from the suspect's relatives or the individual themselves, often leading to arrests or indictments long after the crimes. A prominent example is the 1974 abduction and murder of 17-year-old Carla Walker in Fort Worth, Texas. In 2020, the Fort Worth Police Department partnered with Othram to analyze DNA from Walker's clothing, resulting in the identification of 77-year-old Glen Samuel McCurley as the suspect. McCurley confessed during interrogation and was convicted of capital murder in 2021, receiving a life sentence. This breakthrough, achieved 46 years after the crime, highlighted Othram's collaboration with local agencies to revive stalled investigations. In the 1984 sexual assault and strangulation of nine-year-old Christine Jessop in Ontario, Canada, Othram's genetic genealogy work in 2020 identified Calvin Ray Hoover, who had died in 2015, as the true perpetrator. This revelation exonerated Guy Paul Morin, who had been wrongfully convicted and imprisoned for the crime in 1992 before his 1995 acquittal based on DNA evidence. The case underscored Othram's role in not only naming killers but also rectifying miscarriages of justice through precise DNA matching. Another significant identification occurred in the 1974 abduction, sexual assault, and of five-year-old Siobhan McGuinness in . Othram's analysis of evidence in 2020 pointed to , a transient who had passed away in 2012, as the culprit, closing the case after 46 years and providing closure to the family without the possibility of prosecution. More recently, in 2025, Othram assisted the Shasta County Sheriff's Office in with the 1984 shooting murder of 18-year-old Terrance Arndt and of his 15-year-old female companion near their high school in Burney. Forensic evidence submitted to Othram led to the identification of Roger Neil Schmidt as the suspect via genealogical matching. Schmidt was arrested on July 21, 2025, in , on murder and charges. By 2025, Othram had contributed to the identification of dozens of suspects in cold cases nationwide, predominantly involving homicides and sexual assaults, often resulting in arrests decades after the incidents and demonstrating the transformative impact of genetic genealogy on forensic investigations.

Resolution of unidentified remains cases

Othram's approach to resolving unidentified remains cases involves extracting and sequencing DNA from skeletal or degraded biological samples, generating a comprehensive genetic profile, and applying forensic genetic genealogy to construct family trees on public databases. This process identifies potential relatives through shared DNA segments, which are then verified via direct comparisons or law enforcement collaboration, ultimately confirming the decedent's identity and providing closure to families. The technology addresses significant challenges, such as degraded DNA from decades-old remains exposed to environmental factors like water, soil, or chemicals, where traditional methods often fail due to low quantities or contamination. For instance, Othram has successfully analyzed samples as small as 0.12 nanograms or from chemically damaged bones, enabling identifications in cases spanning 40-50 years. International cases, including those with non-U.S. origins, are handled by tracing global ancestry patterns and coordinating with foreign authorities. Key examples illustrate these successes. In 2020, Othram identified the remains of an 18-month-old girl found in Mississippi's Escatawpa River in 1982, known as "," as Alisha Ann Heinrich, matching her DNA to maternal relatives after prior tests yielded no results. That same year, the unidentified hiker found in Florida's in 2018, dubbed "," was named Vance Rodriguez through genealogy linking him to Louisiana family roots. In 2021, "Beth Doe," a pregnant teenager murdered in in 1976, was identified as Evelyn Colon, whose exhumed remains provided enough DNA for relative matches despite 45 years of degradation. Also in 2021, "Septic Tank Sam," whose burned body was discovered in an Alberta in 1977, was confirmed as Gordon Edwin Sanderson via sequencing that overcame charring and submersion effects. The 2022 identification of "Lady of the Dunes," a woman killed in in 1974, as Ruth Marie Terry relied on Othram's sequencing of chemically preserved tissue to build a viable . More recently, in October 2025, Othram identified remains found in 's Walnut Creek as Rebecca Hakes, a woman, resolving a case from 2024 and demonstrating applicability to fresher evidence. In November 2025, Othram identified remains found in Arizona's Pinal County in 2024 as David Bertschinger. These resolutions have facilitated family reunifications, allowing relatives to mourn and bury loved ones properly, while closing long-standing investigations and sometimes advancing probes. By November 2025, Othram had contributed to over 300 such identifications of unidentified human remains nationwide, underscoring their impact on forensic casework.

Impact and recognition

Influence on forensic science

Othram has pioneered the application of forensic-grade genome sequencing (FGGS), a next-generation sequencing approach that enables analysis of low-input and degraded DNA samples, significantly reducing reliance on traditional short tandem repeat (STR) profiling which often fails with compromised evidence. This shift to single nucleotide polymorphism (SNP) testing allows for the generation of comprehensive genetic profiles from as little as 1 nanogram of DNA, facilitating distant kinship inferences that were previously unattainable in forensic contexts. By developing purpose-built SNP tools for investigative genetic genealogy (IGG) since 2018, Othram has influenced law enforcement standards, with more cases resolved using their methods than any other forensic genetic genealogy approach, prompting updates to guidelines such as those from the U.S. Department of Justice on prioritizing SNP-based investigations. Othram's advocacy has driven policy changes to support expanded access to advanced DNA testing, including contributions to legislative efforts like the Carla Walker Act, which establishes federal grants for forensic in non-homicide s. In , Othram's work aligned with state initiatives securing $1.5 million in funding in 2024 through Rep. Tricia Byrnes's efforts, enabling the to process unidentified remains and resolve multiple cases in 2025 via FGGS. Additionally, Othram has partnered with national programs, such as the Australian Federal Police's National DNA Program, to integrate FGGS into broader database initiatives for unidentified remains and leads, enhancing cross-jurisdictional data sharing. Through platforms like DNASolves.com, Othram has also facilitated for SNP database development tailored to needs. Statistically, Othram's technology has contributed to the resolution of over 600 publicly announced cases across the U.S., as of November 2025, demonstrating its role in accelerating solves for longstanding cold cases that traditional methods could not address. This includes notable progress in Missing and Murdered Indigenous People (MMIP) investigations, where a 2025 partnership with the ' Missing and Murdered Unit has enabled to identify suspects and victims in historically under-resourced cases, such as those on the . Looking ahead, Othram's advancements in familial DNA searching—distinct from traditional IGG by focusing on close relatives in CODIS-like databases—hold potential for proactive crime prevention by generating leads in active investigations before cases go cold. To support this evolution, Othram offers training programs for agencies, including the 120-day Fellowship for forensic genetic genealogy immersion, beta access to secure software like SNPSuite with dedicated support, and sponsored workshops such as countywide sessions on DNA and familial leads.

Cultural and media references

Othram's advancements in forensic have inspired fictional portrayals in television, notably serving as the basis for the 500th episode of : , titled "The Five Hundredth Episode," which aired in October 2021 and dramatized the use of advanced to solve cases through familial matches. The episode fictionalized Othram's laboratory processes and team dynamics, highlighting the ethical tensions of genetic searching in criminal investigations. Additionally, Othram's work has been featured in documentaries and series, such as episodes of that explore DNA breakthroughs in unsolved murders, emphasizing the lab's role in reanalyzing degraded evidence to identify perpetrators decades later. Othram has garnered significant public awareness through extensive news coverage of its case resolutions, particularly in 2024 and 2025, with outlets like ABC13 Houston profiling the Woodlands-based lab's contributions to identifying victims and suspects in long-standing mysteries. For instance, a March 2025 ABC13 report detailed how Othram's sequencing technology resolved cases baffling investigators for years, including homicides and unidentified remains, while a related ABC News 20/20 segment in the same period showcased the lab's facility and its impact on law enforcement partnerships. Podcasts have further amplified this visibility; in October 2025, Criminally Obsessed hosted an interview with Othram co-founder and Chief Development Officer Kristen Mittelman, discussing the company's genealogy-driven approaches to casework and public involvement in DNA submissions. The rise of Othram's methods has sparked debates on implications of familial DNA searching, particularly after high-profile cases where genetic profiles from public databases implicated relatives of suspects without their direct consent. Outlets like in highlighted concerns over the ethical boundaries of such searches, noting Othram's role in generating leads that extended beyond traditional databases and raised questions about and innocent family members' rights. These discussions have continued into 2025, with journalistic analyses framing Othram's successes as a double-edged sword in balancing justice with individual protections. Othram has received recognition for its forensic innovations through prestigious grants and contracts, underscoring its influence on the field. In June 2024, the Research Laboratory's AFWERX program awarded Othram a $1.25 million Phase II contract to enhance for identifying missing service members, building on an earlier Phase I award. Earlier accolades include a 2019 research sequencing grant from the Illumina Accelerator at SXSW, which supported Othram's development of biology-digitizing tools for forensics. In 2025 interviews, such as the Criminally Obsessed episode, Othram leaders elaborated on using preemptively to anticipate and prevent crimes by mapping familial risks and encouraging voluntary DNA uploads to aid investigations proactively. In November 2025, donated nearly $6,000 to Othram to assist in identifying human remains found in Springs, further demonstrating ongoing collaborations with state agencies.
