Man kills wife while on vacation because she laughed at him

A Utah man, Kenneth Manzanares, 39, killed his wife, Kristy Manzanares, 39, aboard an Alaska cruise and told an acquaintance who later walked into the couple's blood-splattered room that he did it because she kept laughing at him in front of their three children, the FBI said in documents released Thursday afternoon.
Manzanares was charged with murder after he was found with blood on his hands
