Fidel Lopez called police in a panic, crying hysterically as Maria Nemeth lay dying on his bathroom floor.
The 24-year-old can be heard screaming in a distressing 911 at the operator: “Hurry up, my girlfriend is in the bathroom!
“Like, I don’t know man, she’s not breathing! She’s gonna die, man! Come on, someone help her!”
According to a police report self-confessed "monster" Lopez admitted he flew into a drunken rage after she cried out the other man's name during "rough sex" inside of their Sunrise apartment's wardrobe in Florida.
He told investigators he shattered a sliding glass door, punching holes into a wall and ripping a closet door off its hinges.
He then returned to 31-year-old Ms 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.
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.
But later Lopez reportedly changed his story and revealed that he became enraged when Ms Nemeth called out her ex-husband's name during sex.
