John Kevin Manville was a 25-year-old veterinary student at UC Davis who was shot dead on March 4, 1980, at the Castilian Apartments in Davis, California. He and his girlfriend, 19-year-old Robin Ehlman, were confronted by Ehlman’s former boyfriend, Daniel Wehner; both Manville and Ehlman were killed in the attack.

Daniel Wehner was arrested, charged, and convicted at trial in June 1981 for the murders of Manville and Ehlman. He was sentenced to 27 years to life. The victims’ families have attended parole hearings and opposed his release.
