Michigan State Police have reported a significant development in the investigation of two cold murder cases dating back to the early 1980s, potentially implicating Charles David Shaw, who died in 1983, as the assailant in both instances.
In a collaborative effort that began in the summer of 2022, Michigan State Police and students from Michigan State University’s School of Criminal Justice reopened the case concerning the 1982 murder of 16-year-old Kimberly Louiselle. Simultaneously, Livingston County investigators were delving into the 1983 disappearance and murder of 19-year-old Christine Castiglione, backed by a grant from non-profit Season of Justice for advanced DNA testing.
Advanced DNA analysis conducted at Othram Inc., a private forensic laboratory in Texas, linked Shaw to Castiglione’s case in 2022. Further investigation in June 2023 revealed a DNA match between Shaw and evidence found in the Louiselle case, establishing a disturbing pattern. Shaw, known to have resided near Castiglione and had multiple run-ins with the law, including an arrest for attempted abduction in 1981, was described by relatives as battling mental health issues and a troubled life marked by sexual addiction.
Authorities are urging individuals with information on potential crimes committed by Shaw from the early 70s until his death in 1983 to come forward to assist in the ongoing investigation.
