Toronto police say investigators used DNA evidence to identify a suspect they believe is a serial killer responsible for the murders of three women in the 1980s and 1990s.

Deputy Chief Robert Johnson said genetic genealogy has linked Kenneth Smith to the decades-old cold case murders of three Toronto women: 25-year-old Christine Prince in 1982; 23-year-old Claire Samson in 1983; and 41-year-old Gracelyn Greenidge in 1997.

The Ontario government’s release of a lengthy report on intimate partner violence is mired in controversy, after the opposition claimed that the study was partly generated by artificial intelligence and that some sources cited in the report do not exist.

Members of the Ontario New Democratic Party said in a news release that AI detection programs “flagged the government’s report as likely being largely AI-generated.” The release also said “multiple sources cited did not exist upon closer inspection.”
