The 13-year-old, who left the scene to get help, is now with family members.
No other identities have been released, and authorities said the investigation is ongoing.
“We are actively trying to find out how (the man) got to that location,” the sheriff said.
About 8:30 a.m., law enforcement was dispatched to an active situation on Bryn Drive, off Highway 9 South, Jarrard said.
“I ask that you be in prayer for the victims, family members involved and all the first responders,” he said.
