— Two people were shot early Sunday during a large party of about 300 people at an Orange County barn venue.

Officers responded to the Smokehouse Valley Farm, located at 5223 Mill Creek Road, around 1:30 a.m. Officials say they were met by large crowds of people leaving a party, where about 150 remained.

According to officials, shots were fired during the party, injuring two attendees.

One of the victims is an 18-year-old woman, who officials discovered behind the party barn suffering from gunshot wounds to the head. The woman was airlifted to UNC Hospital with life-threatening injuries.

A second party-goer was being treated at UNC Hospital in Hillsborough for a gunshot wound to the leg. The victim was treated and released.

Officials say multiple people were involved in the shooting, which likely started with a fight, but the group of 300 was so large that the investigation has been difficult.

“Parties and large crowd gatherings are particularly concerning," said Orange County Sheriff Charles Blackwood. "Crimes that occur at these kinds of events become more challenging for law enforcement to investigate. By the time we’re called, everyone is gone and the people who were there often don’t wish to cooperate or be identified, making it difficult, if not impossible, to gain accurate accounts of what happened from credible witnesses."

According to Blackwood, no arrests have been made, and officers are unsure how many shooters were present or if there were other victims.

“As a parent, we always worry about our children when they are away from us, no matter what their age," said Blackwood. "It’s difficult to make the call that no parent wants to receive; it’s even more difficult when we don’t have all the answers as to what happened to their child.”
