FORT DODGE, Iowa (AP) — A western Iowa man accused of killing his mother and kidnapping another woman says in a written statement to police that he doesn’t remember killing his mother, though he recalls choking her. The Messenger in Fort Dodge reports the statement by 21-year-old Kirk Levin of Early was presented to jurors Wednesday in Webster County during his trial. Levin is charged with first-degree murder in the January death of Marilyn Schmitt. He faces third-degree kidnapping for allegedly abducting 21-year-old Jessica Vega.

The newspaper reports Levin gave the statement after a videotaped police interview where he repeatedly denied killing Schmitt. Levin says in the statement that he is the only person who could have killed his mother. He says he can’t explain his thinking, and he doesn’t remember picking up Vega.
