While Valentine’s Day is usually a time for love and kindness, it proved to be the opposite for a couple in Florida.

Nathan Hemby, 33, of Key Largo was arrested on Sunday after he allegedly wished his girlfriend a “Happy bloody Valentine’s Day” and threatened to cut off her head with a knife and choke her with a belt, according to the Monroe County Sheriff’s Office. His 50-year-old girlfriend was able to lock herself in the bathroom and dial 911. She told officers that Hemby had recently been threatening her with a knife, screw driver, and a box cutter.

According to the victim’s testimony found in the sheriff’s office report, his girlfriend said he held his hand over her mouth, put the knife to her throat, and told her he was going to cut off her head and “grind up her body to sell for meat.”

She also reported that he had threatened to choke her with leather belts hanging on the wall of their apartment and had taken a pair of her underwear, explaining he was going to “add it to his collection of the other girls he had to do this to.”

Officers found all of the weapons and belts described in the apartment, as well as her underwear tucked into his back pocket. Hemby was taken into custody and charged with aggravated assault.
