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

The one-and-a-half page, typed note, titled "Will and Testament," was found on the hard drive of Ryan Jenkins' laptop after the Calgary native hanged himself in a Hope, B.C., motel room, said Buena Park Police Sgt. Bill Kohanek.

He said Jenkins, 32, also apologized to his family for causing trouble but made no mention of the slaying of Jasmine Fiore, 28.

"About half of the letter described how much he loved her, and in the same breath, he would talk about how frustrated she made him and that he felt very jealous about some of her relationships and that frustrated him immensely," Kohanek said.

Jenkins had moved from Calgary to Los Angeles to take part in a TV show called Megan Wants a Millionaire.

Fiore's body was found in a suitcase in a Buena Park trash bin early on Aug. 15. Her nose was broken, she was badly beaten and she was missing the last digit of all her fingers and her teeth — presumably to hamper efforts to identify her.

Police ultimately learned her name by tracking the serial number on her breast implants, but not until Jenkins had a three-day head start on his escape.

Jenkins fled for his native Canada 24 hours after Fiore's body was found. The son of a prominent Calgary architect was found days later in an isolated motel in Hope, B.C., where he had committed suicide.

Kohanek says detectives believe the note was written Aug. 20, the day he checked into the motel and three days before his body was found.
