A Manchester Township man has been charged after authorities say he caused a head-on crash while driving on the wrong side of Route 37 in Toms River, seriously injuring one person before fleeing the scene on foot and later resisting arrest.

According to the Ocean County Prosecutor’s Office, Andrew Gajewski, 30, was charged Monday with leaving the scene of a motor vehicle crash resulting in serious bodily injury, three counts of assault by auto, resisting arrest, and injuring an animal used by a law enforcement agency.

The crash occurred at approximately 8:30 p.m. Monday near Route 37 and Batchelor Street. Officers from the Toms River Township Police Department responded to reports of a crash with injuries and found a 2022 Ford F-150 and a 2021 GMC Acadia with damage consistent with a head-on collision.

Investigators said Gajewski, who was driving the Ford pickup truck, fled the scene on foot following the crash.

The driver of the GMC Acadia was transported to Jersey Shore University Medical Center, where he was listed in stable condition. A passenger in the Acadia and a passenger in the Ford were taken to Community Medical Center, where they were treated and released.

Authorities said Gajewski was later apprehended in a wooded area near the crash site after allegedly resisting arrest and assaulting a police K-9 from the Toms River Police Department. He was transported to Community Medical Center for treatment of injuries sustained during his apprehension.

Investigators said officers observed signs of intoxication, and a blood sample was obtained through a court-authorized warrant as part of the ongoing investigation.

A joint investigation conducted by the Ocean County Prosecutor’s Office Major Crime Unit-Vehicular Homicide Squad, the Toms River Township Police Department and the Ocean County Sheriff’s Office determined that Gajewski had been traveling on the wrong side of the roadway at the time of the crash. Authorities also alleged he had been speeding and driving recklessly shortly before the collision.

In addition to the criminal charges, Gajewski was issued multiple motor vehicle summonses, including reckless driving, careless driving, failure to maintain lane, leaving the scene of a crash causing injury, and failure to report an accident.

Prosecutors said Gajewski remains hospitalized under police custody and will be transported to the Ocean County Jail pending a detention hearing once he is released from medical care.

The investigation remains ongoing, and authorities said additional charges may be filed.
