Phillip Urban, 20, was found fatally shot in his car on a trail at Hopewell Valley Nature Preserve in Hopewell Township, New Jersey, in December. A Pennington School graduate and freshman forward at Post University, he had arranged to meet someone at the preserve; investigators say the meeting was a setup for a robbery. The intended exchange involved a quarter-pound of marijuana for $800, and at some point during the encounter Urban was shot. He was taken to a nearby medical center and pronounced dead shortly after arrival.

Within a week police arrested two juveniles — a 16-year-old from Pennington and a 17-year-old from Hopewell — on charges that include murder, felony murder, robbery, and weapons offenses; their names were not released because of their ages. Prosecutors were reviewing whether to seek a waiver to try them as adults.

Did anyone who knew Phillip or who frequents the preserve notice suspicious activity or people around that December evening?
