A Camden County jury found Detective Mark Campagna guilty on Thursday of endangering another person during the incident in 2023.
While surveillance cameras on the property did not capture the crash, they did capture footage of a man jumping over the driveway gate.
The trooper had been with the state police for over eight years and was a member of the 156th State Police Class, according to the post.
According to the New Jersey Attorney General's Office, the on-duty state trooper was conducting routine patrol duties on Rt. 70 when his marked vehicle collided with a motorcyclist.
New Jersey state troopers in a boat searched extensively over one section of the river, using an underwater camera to aid their search.
State police released images of the three young men they believe are responsible.
