Ad By: Richard L. Smith

Tyzir Hamilton, 22, of Trenton, was found guilty on all charges this week for a double homicide that occurred on Centre Street in Trenton on August 9, 2020.

Mercer County Prosecutor Angelo J. Onofri announced the verdict on September 21, 2023, stating that Hamilton was convicted on two counts of murder, conspiracy to commit murder and weapons charges.

On the morning of the incident, Trenton Police responded to a shooting at 300 Centre Street.

Officials said Trenton Officers discovered two victims: William Irizarry, 18, was found dead on the street, and Julius Vargas, 18, was located inside a nearby market suffering from a gunshot wound and later dying in the hospital.

Thanks to the public's assistance and diligent work by the Mercer County Homicide Task Force (HTF), investigators identified a suspect vehicle, a black Chrysler 300 with Pennsylvania plates, and two shooters. Further evidence revealed that this car had been stolen from Bensalem, Pennsylvania, a week before the murders.

A 9mm Taurus handgun found in the car was later confirmed as one of the weapons used in the crime.

Social media monitoring and forensic analysis also indicated a motive linked to the disrespect shown towards the H-Block gang.

Onofri praised the HTF and the community for their role in solving the case, stating, "For weeks, detectives have methodically pieced the puzzle together, identifying the vehicle and all three suspects.

But the public's help in solving this double homicide was instrumental."

Hamilton was one of three individuals arrested in October 2020 in connection to the murders, with the prosecution thanking the community for their pivotal role in helping "connect the dots" during the investigation.
