Facing murder charges, Fidel Lopez said he flew into a drunken rage after his lover cried out the other man's name during sex, according to a police report.
Investigators say the 24-year-old admitted to shattering a sliding glass door, punching holes into a wall and ripping a closet door off its hinges.
He then returned to 31-year-old Maria Nemeth, who was lying unconscious on the floor, and proceeded to mutilate her with various objects before using his arms to disembowel her.
Before calling 911 just after 3.30am on Sunday, Lopez said he carried her body to the bathroom and splashed water on her face in an attempt to revive her.
He then washed his hands, had a cigarette break outside and called cops to say his lover was not breathing.
Paramedics arrived at the scene to find Lopez sobbing over the woman's naked body lying in a pool of blood, according to the police report.
Ms Nemeth was pronounced dead at the scene less than 30 minutes after Lopez’s initial call to police.
In a police interview, Lopez said he and Ms Nemeth had been drinking tequila in their apartment and at some point began to have sex.
He told investigators the woman had asked him to insert a beer bottle inside her.
Lopez said Ms Nemeth then went into the bathroom to vomit and he later found her having trouble breathing and he called 911.
