The park rangers involved in the shooting at the park last Saturday have been identified as Duane Buck and John Waterman. Buck fired three shots at Daniel McColgan, 43, after he threatened Buck, pointed a handgun at him, and refused to respond to verbal requests to put down the weapon. Neither ranger was hurt in the incident. McColgan is being treated at the Hospital of the University of Pennsylvania and will be charged upon release from the hospital. The incident is being investigated by the NPS and the FBI, with significant assistance from the Chester County District Attorney’s Office Detective Unit, Tredyffrin Township and Upper Merion Township.
