In a groundbreaking application of forensic science, New South Wales police have apprehended a 77-year-old man in connection with a series of alleged sexual assaults that date back over three decades. Robert Wayne Kwan was taken into custody following a search warrant executed in South Kempsey, and he now faces multiple charges, including nine counts of sexual assault and several of kidnapping.
A Decade of Allegations
The charges against Kwan stem from three distinct incidents occurring between 1991 and 2002. The first alleged assault involved an 11-year-old girl in western Sydney, followed by an attack on a 16-year-old girl in the Illawarra region in 1996, and a further incident involving a 26-year-old woman in Dubbo in 2002. These cases had remained unresolved for years, until recent advancements in DNA technology provided a new avenue for investigation.
Forensic Investigative Genetic Genealogy at Work
NSW detectives employed a sophisticated method known as forensic investigative genetic genealogy (Figg) to connect the dots across these historical cases. This innovative approach enhances traditional DNA profiling, which typically examines 21 genetic markers, by analysing hundreds of thousands of markers. This allows law enforcement to identify potential familial connections, even extending to fourth cousins.
The process involved comparing DNA profiles from the unsolved cases against two publicly available genealogy databases, GEDmatch PRO and FamilyTreeDNA. The data yielded a close relative of Kwan, significantly narrowing the search and ultimately leading to his arrest. The use of Figg technology marks a pivotal moment for NSW police, making Kwan’s arrest the first of its kind facilitated by this method in the state.
A Call to the Public
Detective Superintendent Jayne Doherty, head of the sex crimes squad, has urged the public to consider “opting in” on genealogy websites to aid law enforcement in solving serious crimes, including homicides and sexual assaults. She emphasised the importance of community cooperation in the pursuit of justice for victims.
Doherty noted that other Australian states are also adopting this technology, reflecting a broader trend in law enforcement to utilise innovative methods for resolving cold cases. She affirmed that, regardless of the time elapsed, detectives remain committed to identifying those responsible for sexual offences.
Court Proceedings and Next Steps
Kwan did not apply for bail during his initial court appearance and is scheduled to return to Kempsey Local Court on 22 April. As the investigation continues, his case serves as a reminder of the potential for modern technology to bring closure to long-standing mysteries in the realm of criminal justice.
Why it Matters
The application of advanced DNA technology in this instance not only underscores the evolving capabilities of forensic science but also raises critical discussions about privacy and ethical considerations surrounding genetic data. As more individuals engage with genealogy platforms, the balance between aiding crime-solving efforts and safeguarding personal privacy becomes increasingly pertinent. Kwan’s arrest signifies a step forward in delivering justice for victims of historic crimes, demonstrating that the passage of time does not diminish the resolve of law enforcement to seek accountability.
