Officers responding to the apartment in Sunrise, Florida said they found Lopez crying in the bathroom next to the 31-year-old's naked body, which was in a pool of blood.

Police say Lopez told investigators that they had been having sex after drinking tequila when Nemeth went into the bathroom, vomited and collapsed.

But following further questioning, police say Lopez revealed that he became enraged with Nemeth when she called out her ex-husband's name twice as they had sex in a closet.

Police say that he told them he started smashing things in the apartment out of anger and when he returned to the closet, he found Nemeth passed out.

He told police he became a "monster" and started putting objects inside of her. He said he then put his hand inside her before pulling out intestinal matter, according to an arrest report cited by CBS Miami.
