Investigators say a southern California chef has confessed he "slow cooked" his wife's body for days in 2009, then disposed of the remains. "For some reason I just got violent," David Viens, a chef who ran a restaurant in Lomita, told cops. He said he bound wife Dawn's hands and feet and covered her mouth with duct tape, and the next morning she was dead, according to investigators. Viens then stuffed her body in a 55-gallon drum of boiling water, they testified yesterday in Viens' trial. "I just slowly cooked it, and I ended up cooking her for four days," Viens said in a taped police interview played for the jury. He mixed what remained with other waste and dumped it, reports the Los Angeles Times. Viens has pleaded not guilty; Dawn's body was never found. (More crime stories.)
