Lopez told detectives he became a "monster" when Nemeth called out her ex-husband's name two times while they were having sex. He said hearing someone else's name during sex upset and enraged him, investigators said.

Lopez said he left Nemeth in the closet where they were having sex and started breaking things throughout the apartment, smashing the rear sliding glass door and punching holes in the walls, police said.

He went back to the closet where Nemeth was lying unconscious and he started inserting a beer bottle, a flat iron for hair, and both fists inside of her, investigators said.

Lopez said he inserted his arm up to his elbow and ripped out part of her intestines, detectives said.

Detectives said they found a half empty bottle of 1800 Tequila and cut limes in the kitchen and signs of a physical struggle and foul play.

Actually, now that I think of it, what that guy did took guts.
