Sex Offender Sentenced For Slashing Of Girlfriend, Stabbing Her Roommate On LI: DA Suffolk DA calls his "sustained and remorseless assault" of the victims "unconscionable and unacceptable."

RIVERSIDE, NY — A sex offender with no known last address was sentenced to 14 to 16 years in prison in connection with strangling and slashing his girlfriend and stabbing her roommate back in 2023, Suffolk District Attorney Ray Tierney said Thursday.

Abraham Crosby, 50, went to his girlfriend's apartment in Patchogue while drunk and high on drugs, began arguing with his girlfriend, and her roommate tried to calm the situation, but he became violent and began strangling his girlfriend until she lost consciousness, prosecutors said.

He then turned to the roommate and stabbed her in the back, causing a punctured lung, according to prosecutors.

When Crosby's girlfriend regained consciousness, she tried to run, but he slashed her head with a knife, causing a large laceration to the scalp which required 12 staples to close, prosecutors said, adding that Crosby fled and the two women ran to a neighbor for help.

When police responded, they found Crosby a short distance from the apartment, and when officers placed him under arrest, one recovered metal knuckles from his pocket, prosecutors said.

Crosby is a level three sex offender stemming from a 2006 conviction of second-degree course of sexual conduct against a child in the Second Degree, a felony.

Tierney said Crosby's "sustained and remorseless assault of the victims here is unconscionable and unacceptable."

"Domestic violence cannot be tolerated," he said. "I commend everyone in law enforcement who worked tirelessly to protect both the victim and the community from further violence by this defendant."

Crosby was convicted in September after a bench trial on two counts of second-degree of assault, one count of second-degree strangulation, and third-degree criminal possession of a weapon, as well as criminal obstruction of breathing or blood circulation. He was also found guilty of third-degree assault.

He represented himself but attorney, Christopher Brocato of Central Islip, acting as his legal advisor.

Brocato could not comment on the case.
