A woman killed one person and wounded five more before fatally shooting herself as police approached her on Sunday morning, North Carolina authorities said.

One victim was found wounded in a parking lot of Guilford Technical Community College near Greensboro. The gunwoman shot herself in a car and was pronounced dead at a hospital, said Guilford County Sheriff BJ Barnes. A wounded victim was in the back seat, he said.

Deputies then went to the suspect's nearby home, where they found one person dead and three more wounded. The victims ranged in age from 9 to 40 and four were younger than 18, Barnes said. They all knew each other and some are related, he said. Their identities were not released.

The sheriff says three of the wounded were on life support late Sunday afternoon. Deputies say no more information will be released until Monday morning.

"We're trying to figure out exactly what did happen here," Barnes said at a news conference. "The only thing we know is we have a large number of gunshot victims."

The shootings began happening around 9 a.m., and police have recovered several guns, Barnes said.

A two-page note was found at one of the shooting scenes in Pleasant Garden, but Barnes could not specify what it said.
