Deer Park woman blows off boyfriend’s hand, gets 18 years in prison

A Deer Park woman who hurled an explosive device into her sleeping boyfriend’s bedroom — an attack that blew off most of his hand and some of his arm — has been sentenced to 18 years in prison, authorities announced Thursday.

Keyonna Waddell, 35, was handed down her punishment Wednesday by Suffolk County Supreme Court Justice Richard Horowitz, following her jury trial conviction in April of first-degree assault and first-degree criminal possession of a weapon.

Prosecutors said Waddell threw the device — described during her trial as looking like a stick of dynamite — into the victim’s bedroom on the night of March 22, 2024, while he slept.

The victim woke to a hissing sound, and when attempts to smother the device failed, he grabbed it and tried to toss it out the window, prosecutors said. But it detonated in his hand.

Bleeding and missing most of his hand, the man staggered to the end of his driveway, where he spotted Waddell fleeing on foot, authorities said.

He was rushed to Nassau University Medical Center, where surgeons amputated the remainder of his hand and a portion of his arm.

Investigators later learned Waddell had threatened the victim with dynamite numerous times in the months leading up to the attack.

“This sentence is a measure of justice for a victim who survived an act of unspeakable domestic violence in his own home,” Suffolk County District Attorney Raymond Tierney said.

In addition to her prison term, Waddell was sentenced to five years of post-release supervision.
