A Wisconsin man has been charged with strangling his teenage stepson and leaving the body in a minivan in a Walmart parking lot.

Thirty-seven-year-old Charles A. Avey of Grafton was charged Tuesday with first-degree intentional homicide and felony bail jumping. He is scheduled to appear in court Tuesday afternoon.

The criminal complaint says Avey killed 14-year-old Cody A. Reetz on Sunday.

Avey's ex-wife told investigators Avey was trying to get back at his wife and her former husband, who is Cody's birth father. She says he admitted killing Cody and asked her to drive him to the sheriff's department so he could turn himself in.

Online court records didn't list an attorney for Avey. Police didn't immediately know whether he had a lawyer.
