Erie County District Attorney Michael J. Keane announces that Thomas F. Sibick, 40, of Williamsville, was arraigned this morning before State Supreme Court Justice Deborah A. Haendiges on an indictment charging him with the following offenses:
- One count of Criminal Possession of a Firearm (Class E felony)
- Five counts of Criminal Possession of a Weapon in the Third Degree (Class D felonies)
- One count of Criminal Mischief in the Fourth Degree (Class A misdemeanor)
It is alleged that on June 8, 2026, the defendant and the victim were involved in an argument at a residence in the Village of Williamsville. While inside of the garage, the victim attempted to leave in a vehicle. The defendant allegedly pushed the car door open and grabbed the victim’s purse and phone charging cable, which damaged the cord. The defendant is accused of intentionally causing damage to the victim’s cell phone screen protector by throwing the phone onto the ground. After the victim left the home, she reported the incident to police.
At the defendant’s arraignment in Amherst Town Court, a temporary order of protection was issued on behalf of the victim, which required all firearms to be turned over to police. During the investigation, police allegedly seized several firearms and extended magazines from inside of the home, which included two semi-automatic rifles exhibiting assault weapon characteristics and three loaded large-capacity cartridge magazines. Police also separately recovered an upper and lower receiver that together created an operable semi-automatic rifle with assault weapon characteristics.
Sibick is scheduled to return for a pre-trial conference on Wednesday, September 2, 2026, at 9:30 a.m. He remains held without bail. A temporary order of protection, issued on behalf of the victim, remains in effect.
If convicted of the highest charge, Sibick faces a maximum sentence of 7 years in prison.
DA Keane commends the Amherst Police Department for their work in this investigation.
The case is being prosecuted by Assistant District Attorney Krista R. DeAntonis of the Domestic Violence Bureau.
As are all persons accused of a crime, the defendant is presumed innocent until proven guilty in a court of law.
