Florida man disemboweled his girlfriend during crazy sex

Discovery documents have been released in the grisly death of a woman allegedly murdered by her boyfriend during sex.

Suspected killer Fidel Lopez underwent a grilling from Sunrise Police detectives during an hours-long interrogation last September.

Officers questioned Lopez after the mutilated body of his girlfriend Maria Nemeth, 31, was found inside their apartment.

Lopez said the couple was drunk on tequila and had some rough sex, but then Nemeth felt ill and went to the bathroom. Lopez said he called 911 for help after finding her.

But a series of police interrogation videos just released to CBS4 News on Thursday show that investigators were not buying his story after finding an incredibly bloody scene at the apartment.

“Fidel, this was not a case of rough sex,” one of the detectives said.

For hours, Lopez denied to police that he hurt Nemeth.

“You have to do the right thing and tell the truth,” a detective said.

“I’m doing the right thing,” Lopez shot back.

Lopez maintained that he loved Nemeth.

“She’s a good girl,” he said. “She’s a perfect girl, man. She’s my love.”

Then, a short time later, Lopez admitted that he snapped after Nemeth called him by her ex-husband’s name during sex.

“She changed my name,” he said. “She called me the name of the other (expletive) guy. And she said it twice and she was wrong and she was confusing me with him. At that point, I get mad,” he said. “I get really, really mad.”

Police say Lopez admitted to becoming a “monster” and destroying the apartment, then disemboweling Nemeth.
