ANDERSON, S.C. (AP) - Authorities say a 17-year-old man has drowned while swimming at an Anderson city park on Hartwell Lake.

Investigators said Marco Cramer was part of a group that swam about 100-feet out to a buoy on the lake Saturday afternoon. Cramer disappeared as the group headed back to a dock. The water is about 20-feet deep around the buoy.

Authorities say divers found the teen's body about 30 minutes after witnesses called 911.

The coroner's office plans an autopsy Monday, but says all evidence indicates the teen accidentally drowned.

Cramer was a sophomore at Powdersville High School, and school officials say counselors will be on hand Monday to talk to students.
