LOS ANGELES — A chef who told police he boiled his wife’s body for four days to hide evidence of her death was convicted Thursday of second-degree murder.
David Viens showed no reaction as the verdict was read.
In a recorded interrogation played by prosecutors at trial, Viens can be heard saying he cooked the body of his 39-year-old wife, Dawn, in 2009 until little was left except her skull.
‘‘He treated her like a piece of meat and got rid of her,’’ said Karen Patterson, the couple’s best friend.
She was the key witness in Viens’s trial and the one who prodded police to investigate her friend’s disappearance.
At a news conference, she urged others to take heed of domestic abuse among friends and call police. She apologized for failing to call 911 when Dawn Viens contacted her after an incident of abuse but begged her not to call police.
‘‘Maybe you have to go beyond your friend’s trust and try to save lives,’’ she said.
