New Jersey State Police and the Monmouth County Prosecutor's Office are looking for a suspect and witnesses to a shooting that left two people critically wounded outside a hip-hop concert in Monmouth County.

The shooting happened late Monday in the parking lot outside the PNC Bank Arts Center in Holmdel, causing panic among the crowd attending a show by Big Sean and J. Cole.

State troopers, using K-9 units and a helicopter, scoured a wooded area near the amphitheater.

State police said on their Facebook page early Tuesday that the victims are in critical condition at Jersey Shore University Medical Center. Their names and ages have not yet been released.

Monmouth County Crime Stoppers is offering a $5,000 reward for information leading to an arrest.

Anyone with information is asked to contact New Jersey State Police detectives at 732-441-4550 or Monmouth County Crime Stoppers at 800-671-4400.
