SUMMERVILLE — A man was shot twice this morning about 10 a.m. at the South Main Street Mobile Home Park near Summerville High School, leading authorities to place Summerville High School on lockdown as a precaution.

The school came off lockdown about 11:45 a.m.

Summerville Police Department Capt. Jon Rogers said that two men were having an argument at the mobile home park when the victim got into a white Toyota Camry.

The suspect then fired two shots that went through the windshield of the vehicle.

The victim, though injured, was able to drive the car a couple of streets over to a friend's house in the mobile home park and knock on the friend's front door.

A witness, who declined to be identified, said the victim was alert and moving though he was shot in the head and arm.

Police are seeking the suspect, who is described as a black male about 5-feet-6-inches tall wearing black shorts and a white shirt.
