Amy Marie Derewitz, 22, vanished from Dearborn Heights, Michigan after a visit to the home she had recently shared with her ex-fiancé, David Anthony Kniga. The last confirmed sighting was June 3, 2001, when she went to retrieve mail. An argument occurred; Amy left and returned shortly afterward. A new girlfriend at the house told investigators she saw Kniga take Amy into the basement and, as she left the home, saw Amy on the basement floor gasping and severely injured. The girlfriend did not call for help and Amy was never seen again.

Amy’s teal green 1994 or 1995 Ford Escort was found abandoned in a park parking lot on June 7; her purse, ID, and personal items were not recovered. She was described as dependable, with no financial activity or efforts to start a new life after her disappearance. Authorities later charged Kniga with second-degree murder and he ultimately pleaded to manslaughter, saying he placed Amy’s body in a dumpster near the former VA hospital in Allen Park; searches did not recover her remains.

Does anyone have information about Amy’s last visit to the Detroit Street home or about her green Escort being parked near Ten Eyck Park in early June 2001?
