A 21-year-old man from Long Island faces attempted murder charges after allegedly shooting his sister in the face with a crossbow, according to Nassau County police.

Suspect Samy Sedhom, of Lawrence, was also in possession of a samurai sword when he was arrested for trying to kill the 28-year-old victim on Friday.

Police were called to a home on West Avenue in Lawrence just before 9:30 p.m., where they discovered a woman bleeding from a laceration on the right side of her face, as detailed in a police press release.

Investigators quickly concluded that the man, identified as Sedhom, had fired an arrow from a crossbow, narrowly avoiding a potentially fatal injury to his sister.

According to WABC, Sedhom allegedly waited in his car across the street from his family’s residence for his older sister to come back from the gym. As she parked in the garage and attempted to close the door using a code, an arrow grazed her face.

When police arrived, they reportedly found the arrow embedded in the garage’s back wall.

The victim was transported to a hospital, where she was reported to be in stable condition as of Tuesday.

The Nassau County District Attorney’s Office claims the siblings had been arguing about the temperature in their home, according to court documents obtained by News 12 Long Island.

“She liked to keep it cooler, he wanted it warmer,” said DA Anne Donnelly.

Investigators reportedly said the suspect confessed to plotting the murder of his sister since Christmas. A samurai sword and the box from the crossbow were found in his bedroom, reported WABC.

Sedhom was arrested without incident Saturday and arraigned on Sunday, according to court records. He’s being held without bail and is due back in court on Wednesday.

Sedhom pleaded not guilty to an attempted murder charge that carries a maximum prison sentence of 25 years. He’s also accused of assault, stalking, criminal possession of a weapon and tampering with physical evidence.

His sister has been granted a temporary order of protection, court records show.

Donnelly said Sedhom could have been facing murder charges if the arrow had struck his victim just a few inches over.
