There are violent crimes, and then there are incidents like this that make you rethink humanity. A Florida man is in police custody after reports say he disemboweled his girlfriend because she called out the wrong name during sex—twice. The Sun Sentinel reports that 24-year-old Fidel Lopez dialed 911 at 3:39 a.m. Sunday morning to report that his girlfriend, Maria Nemeth, had trouble breathing.

Details from the arrest report say Sunrise police found Lopez crying out for help next to the 31-year-old’s body. He first told investigators during questioning that that he and Nemeth had participated in rough sex and that she went into the bathroom, vomited and collapsed. Upon further questioning, Lopez came clean and informed police that he turned into a "monster" when Nemeth called out her ex-husband's name during intercourse. The details of what happened next are not for the faint of heart. According to reports: 

After he returned to the closet where Nemeth was lying unconscious, he inserted a beer bottle, a flat iron for hairstyling, and both fists inside of her. He then inserted his arm up to his elbow and ripped out part of her intestines. Next, Lopez carried her into the bathroom and splashed water on her face but Nemeth never regained consciousness. He told police he washed the blood off his hands in the bathroom sink, went to the porch to smoke a cigarette and then began to panic. After trying to clean up the apartment, he allegedly checked on Nemeth in the bathroom, saw that she wasn't breathing and dialed 911.

Detectives say they found signs of foul play, along with a half empty bottle of 1800 Tequila and sliced limes in the kitchen. The bathroom door had been ripped off its hinges, and blood and tissue were present in the bathroom, bedroom closet, and smeared on walls and doors. The apartment also had holes in the walls and a smashed sliding glass door. According to Lopez, he left Nemeth in the closet where they were having sex and started breaking things throughout the apartment. 

Nemeth was pronounced dead at 4:02 a.m. on Sunday morning. Lopez was arrested at 2 p.m. that same day, charged with first-degree murder.
