The adult man, who was sitting in the front seat of the vehicle, appears to be the ‘parent of the three children’, officers at the scene told WXIA-TV.
Police have not identified the victims, but confirmed to DailyMail.com that the victims included two girls and a boy who appear to be elementary and middle school aged.
Officers are investigating the case as a murder-suicide, but say final determination will be made by the Medical Examiner’s Office.
The bodies were found by an officer who was carrying out a routine check at the park. The patrolman reportedly ‘stumbled upon’ a ‘suspicious vehicle’ parked along the pedestrian trail.
