Man Breaks Into Ex-Girlfriend’s Home After Breakup, Allegedly Stabs Her Son Seven Times

A Patchogue man is facing attempted murder charges after stabbing his ex-girlfriend’s 22-year-old son. The incident allegedly occurred after his girlfriend broke up with him.

In a press release published by Suffolk County District Attorney Raymond A. Tierney. Tierney on Friday, May 1, the defendant, identified as Robert Schreiber, 42, of Patchogue, was indicted for "Attempted Murder, Burglary, and other related charges."

According to the press release, the incident unfolded on April 17, 2026, when the defendant's long-term girlfriend locked him out of her house in Patchogue.

The man allegedly snuck into the house through an unlocked window the following morning at around 8:00 a.m.

He kicked in the door to his ex-girlfriend’s son’s room and stabbed him seven times in the head, neck and shoulder.

Authorities were called after the victim’s family members intervened, prompting the man to escape the scene.

However, located and taken into custody at the scene, and was found with the knife used in the attack, authorities added.

“Officers arrived and located the victim, who was then transported by ambulance to NYU Langone Hospital where he received numerous staples to close his stab wounds,” the press release added.

“This was a violent attack on a young man in his own home. Domestic violence does not always end when a relationship does, it often escalates. We will aggressively prosecute this defendant and seek justice for the victim and his family,” said District Attorney Tierney.

Justice Collins set bail at $100,000 cash, $1,000,000 bond, or $1,000,000 or a partially secured bond as the case remains ongoing.

“This case is being prosecuted by Assistant District Attorney Johanna Poremba of the Child Abuse and Domestic Violence Bureau, and the investigation was conducted by Detective Eric Cox of the Suffolk County Police Department’s Fifth Squad,” the press release stated.

Schreiber is facing multiple charges, including second-degree attempted murder, first-degree burglary, first-degree attempted assault, second-degree assault, fourth-degree criminal possession of a weapon, endangering the welfare of a child and second-degree harassment. If convicted, he could face up to 25 years in prison.

The 42-year-old is due in court on May 28, 2026.

A similar incident occurred in March last year, when David Huff shot his 11-year-old son, Jeremiah Huff and girlfriend, Yeraldith Tschudy, 32, in Syracuse, New York.

Jeremiah managed to call his mother after he was shot. "To be on the phone listening to your son murdered, she'll never get over that. Ever," Onondaga County District Attorney William Fitzpatrick stated, per 13 WHAM.

In his recent court appearance on Tuesday, April 28, where he pleaded guilty to two counts of murder, David was caught smirking and smiling.

"You find this funny?" the judge asked him, the New York Post reported. In response, David shook his head before replying, "It's just a joke stuck in my head, go ahead."

"I’m focused on the family. I’m focused on Jeremiah. I’m focused on Ms. Tschduy. I could care less what his reaction to any of this is,” Assistant District Attorney Rob Moran told CNY Central. "I don’t have enough bandwidth to put any time into worrying about his reaction to these things."
