Suspect Charged in 2006 Scarborough Cold Case with Aid of Forensic Technology

Toronto police have announced the arrest of a 43-year-old Hamilton man charged with first-degree murder in a cold case from 2006. The victim, 21-year-old Patrick Santos, was discovered deceased at a Scarborough residence in September of that year.

Investigators initially collected DNA evidence from the scene, but it did not produce a match in national databases at the time. The case saw renewed progress in 2020 when police employed genetic genealogy. This advanced investigative approach helped identify a person of interest last year, leading to the collection of suspect DNA and a subsequent confirmation of a match with the evidence found at the scene.

Det. Sgt. Stephen Smith stated that the use of genetic genealogy has proven to be a transformative tool in solving previously intractable cold cases. He conveyed the resolution to the victim's mother, who expressed relief that an individual would be held accountable for her son's death.

While the motive remains under investigation, police suspect the homicide may have stemmed from a disagreement between associate groups. Authorities believe multiple individuals could be involved and are continuing to ascertain the sequence of events leading to the murder and the connection between the accused and the victim. The investigation is ongoing, and police are appealing to the public for any information.

This development highlights the increasing effectiveness of forensic science in resolving long-unsolved crimes, bringing a measure of closure to victims' families.
