A 47-year-old western Michigan man has pleaded guilty to lying to police about the disappearance of a gas station clerk. Kevin Bluhm appeared Friday in Muskegon County Circuit Court. Bluhm is the cousin of Jeffrey Willis, who is being investigated in the 2013 disappearance of Jessica Heeringa, a clerk in Norton Shores. Authorities say Bluhm told police Willis was responsible, but later told police he made it up. He will be sentenced in September. Willis is charged with abducting a 16-year-old girl in April and the 2014 slaying of 36-year-old jogger Rebekah Bletsch in Dalton Township. Bluhm waived a preliminary examination last month on a charge of lying to police in the Bletsch case.
