Sgt. Stephen Jones, a state police spokesman, said the gunman - whose name was not disclosed - had sustained what appeared to be a self-inflicted gunshot wound to the head, but was still alive and was taken to a nearby hospital. But further details on his condition were not disclosed.
Jones said several troopers entered the apartment at the Versailles complex in Ewing shortly before 8 p.m., nearly eight hours after the standoff had started. Authorities had not been able to make contact with the gunman during the standoff, and Jones said it wasn't immediately clear if the man - who lived at the complex - had sustained his head wound earlier in the day or shortly before the standoff ended.
It's believed that the gunman shot another man who was found in a complex parking lot around 12:30 p.m., shortly after police responded to reports of shots fired. But emergency crews couldn't get to the man during the standoff, due to concerns the gunman would open fire again.
Several residents were evacuated from the complex shortly after the incident began, while others were urged to stay indoors and away from windows. But no other injuries were reported, and all residents were expected to be allowed back in their units by late Thursday night or early Friday.
Jones said he did not have any information regarding the initial shooting victim, including where or how many times he had been shot. He said the victim's name would not be released until his family members had been notified.
A motive for the shooting remained under investigation Thursday night, Jones said.
