The man, identified by authorities on Tuesday as 37-year-old John Spincken, drove away with the kids in his SUV as police soon tracked him to the town of Wanaque using his cell phone’s GPS signal. At about the same time, state police were informed of a possible suicide attempt on an I-287 overpass.

While early reports suggested Spincken jumped into a river, New Jersey State Police said in a statement that "based on the preliminary investigation, detectives have determined that the father intentionally jumped with the two children... into a wooded area near the Wanaque River."

The man had somehow scaled an 8-foot fence with the boys in order to jump off the overpass, according to CBS New York.

While Spincken was pronounced dead at the scene, the boys miraculously survived.
