A self-described MS-13 gang member from Bay Shore appeared in court Monday to face attempted murder charges after beating his ex-girlfriend with a stapler, kicking her in the face and stabbing her with scissors, Nassau police said.

Kenny Cruz, 30, was arraigned Monday at First District Court in Hempstead. Cruz, who was taken into custody Sunday in front of his home, also faces charges of robbery, assault, criminal possession of a weapon, menacing and criminal mischief in connection with the attack, which took place Thursday night in Hempstead, said Det. Vincent Garcia, a Nassau police spokesman.

The case was adjourned until Thursday and a judge issued a temporary restraining order against Cruz, according to court records. He remained in custody Monday with a cash bail of $350,000, or a $700,000 bond, the records showed.

Garcia said that at 6:30 p.m. Thursday, Cruz’s ex-girlfriend, 32, of New Cassel, visited the man’s mother at her business at West Columbia Street to discuss financial support for the child, 14, she had with Cruz, Garcia said.

Police said Cruz confronted the woman, punching her in the face and throwing her to the ground. He kicked her, rupturing a lung, a spokeswoman said, and hit her in the head with the stapler several times, cutting her deeply enough to expose her skull. He also kicked her in the face and stabbed her three times in the stomach, the police spokeswoman said.

When the woman tried to call 911 from her cellphone, according to police, Cruz took it away. He forced her to remain at the site of the attack, pointing the scissors at her, and when his mother tried to intervene, Cruz threatened her with the scissors. He later fled, the police spokeswoman said.

The ex-girlfriend escaped and drove herself home, and her mother took her to a hospital. She required “immediate emergency surgery,” Garcia said.

“This was a violent, violent act,” he said.

When asked how the woman could have driven herself home, given the extent of her injuries, Garcia answered: “Adrenaline.”

There was no reported history of domestic violence between Cruz and the woman, Garcia said. Cruz has tattoos associated with the MS-13 gang, Garcia said.

The police spokeswoman said no information was available about the woman’s condition.
