Second Michigan murder suspect arrested in young woman's deadly abduction

Harvey Castro talks about how AI could be used in cold cases and the symbiotic relationship between AI and a detective. Michigan authorities have made a second arrest in connection with the 1980 murder of 21-year-old Karen Umphrey. The St. Clair County Sheriff's Office on Feb. 8 announced the arrest of Anthony Harris, 63, in connection with Umphrey's murder – approximately two months after they arrested Douglas Laming, 70, in the same case. "Working with the Michigan State Police and Othram, a company specializing in forensic genetic genealogy, information was uncovered that previously would have been impossible to find," the sheriff's office said in a December 2023 press release announcing Laming's arrest. "From there, St. Clair County Sheriff's Office detectives spoke to many people that were connected to the victim and suspect over 40 years ago, gathering information and making vital connections."
