Police were contacted by Regional Medical Center staff at about 2:45 a.m. when the victim of a shooting limped into the emergency room, San Jose police Sgt. Jason Dwyer said.
The victim, a man in his early 20s, told police he had been at a party in South San Jose where he was involved in a scuffle and shot in the lower leg.
His injury was not life threatening.
The victim has been uncooperative and did not tell police how he arrived at the hospital or any details about the cause of his injury, including a motive or who might have been involved.
The shooting has not been determined to be gang related, though Dwyer said the area has seen incidents of gang activity in the past. The shooting remains under investigation.
