UPPER DEERFIELD TOWNSHIP — A 76-year-old Cumberland County man was shot and critically injured by NJ state troopers during an exchange of gunfire that took place when the officers were directed to respond to an incorrect residence for a 911 call, authorities said Saturday.

According to the Attorney General's office police were dispatched to a rural, single-family residence after police dispatchers received a 911 call from a cell phone at 11:30 p.m. Friday night.

"An attempt was made to trace the cell phone so that officers could check on the well-being of the caller, and the call appeared to have been placed from the address where the shooting occurred in the 300 block of Centerton Road in Upper Deerfield Township," the Attorney General's office said in a statement Saturday afternoon.

The address was later found to be incorrect, police said, but prior to making that determination, two state troopers from the State Police Bridgeton Station responded to the residence in separate vehicle "to see if assistance was needed."

Police then attempted to communicate with the residents, who were identified as 76-year-old Gerald Sykes and his wife. Troopers went to the rear of the home and knocked on the sliding glass door, shining their flashlights inside the home and informing the homeowners that they were police officers and were responding to a 911 call, according to authorities.

"At that time, there was an exchange of gunfire through the sliding glass door in which one of the troopers fired four rounds from his service 9mm handgun and Gerald Sykes fired a single round from a shotgun," the Attorney General's office stated.

Police say Sykes was struck by multiple rounds and stayed inside the home, contacting their daughter by phone. The occupants and their daughter both called 911 and dispatchers convinced Sykes to exit the house so he could be given medical treatment, police said. The Attorney General's Office said the man was flown to Cooper University Hospital in Camden. He is currently listed in critical but stable condition.

One state trooper also suffered a "graze wound," the Attorney General's office said, that police believe was either caused by a bullet from Sykes' shotgun or by flying glass when the sliding glass door shattering after the shotgun blast. He was treated at Inspira Medical center in Vineland and released.

Authorities said the incident is still being investigated by the Attorney General’s Shooting Response Team.
