DNA and Genetic Genealogy Solve Three Toronto Cold Case Murders
On December 11, 2025, Toronto police announced that forensic testing and genetic genealogy had conclusively linked Kenneth Smith, who died in 2019, to three historical homicides in the Toronto area. The identifications bring renewed attention to the power of updated DNA technology, and they raise the possibility of additional victims and new investigations for families and the community.
Toronto police announced on December 11, 2025 that forensic testing and genetic genealogy had conclusively identified Kenneth Smith as the person responsible for three long unsolved homicides in the Toronto area. Smith, who died in 2019, was linked to killings spanning from 1982 to 1997, according to the police announcement.
The three victims are identified in police statements as Christine Prince, age 25, who was sexually assaulted and found in the Rouge River in 1982; Claire Samson, age 23, who was shot to death in 1983; and Gracelyn Greenidge, age 41, who died of blunt force trauma in her apartment in 1997. Investigators said Smith lived and worked in Toronto at the times of the murders and had a prior history of sexual assault. Police also said there may be additional victims connected to Smith.
The revelation underscores the growing role of updated DNA testing and genetic genealogy techniques in resolving cold cases that have frustrated families and investigators for decades. Genetic genealogy has become a practical investigative tool, allowing forensic teams to reanalyze evidence with newer technology, create family leads where none existed before, and focus inquiries to identify suspects even when traditional methods stalled.
For affected families and the broader community the identification has immediate emotional and investigative consequences. Families may find a measure of closure while also confronting renewed attention to traumatic events. Neighbors and community groups should expect police to review related unsolved cases and to seek information from anyone with potential leads. If you have information about the cases or other unresolved deaths, contact the Toronto Police Service to provide tips.
This development also matters for how communities think about public safety and historical accountability. The technical advances that made these identifications possible offer a pathway to reexamine other unsolved crimes, and they signal that evidence preserved from past investigations can yield answers many years later.
