(Springfield, OR) -- DNA genealogy tracing has helped solve a 31-year-old cold case from Springfield. In 1995, the body of 33-year-old Joni Grigsby was found along a river. DNA was collected, but at the time the technology didn't exist to identify a suspect. In 2023, the DNA was sent to an outside lab that traces genealogy and they identified the suspect as Roy Gomes. He was shot and killed by Sacramento Police in 2004. Direct DNA testing confirmed Gomes as the suspect in Grigsby's murder.
