A reality show contestant charged in the gruesome slaying of his ex-model wife left a suicide note on his laptop that says he considered her the love of his life but thought she was cheating on him, a police spokesman said Monday.

The 1 1/2-page typed note, titled "Will and Testament," was found on the hard drive of Ryan Jenkins' laptop after the former VH1 contestant hung himself in a Canadian motel room, said Sgt. Bill Kohanek.
