Police are investigating how a teenager fell to his death off a cliff at Palisades State Park in New Jersey on Friday.
Authorities say the 16-year-old boy was walking with a friend at around 9 p.m Friday at the Fort Lee park when he fell backwards down the 300-foot cliff.
Crews, including a high-angle rescue team, worked for hours Friday night to rescue the teen, but the darkness and height of the cliff made it difficult.
The victim was pronounced dead on the scene by paramedics once rescue crews retrieved him.
"No idea how he fell, no idea why he was up there so late at night in the dark," said Chief Pete Sabatino, from the Fort Lee Fire Department.
Officers determined that victim was beyond a safety railing on the Palisades Parkway, which was put in place to prevent people from being close to the edge.
The victim has not yet been identified. The investigation is ongoing.
