Excerpts of 911 call in Sullivan's Island teen drowning

SULLIVAN'S ISLAND, SC (WCSC) - Authorities have released the 911 call made by a teenager who called for help after returning to the beach on Sullivan's Island and finding his friends, one of whom had drowned, had disappeared.

"I'm out on the beach and my friends were out swimming out on the sandbar," said Joseph Riddle to an emergency dispatcher Tuesday afternoon."And I can't see them anymore. They've been gone for a while."

Riddle said that he had been swimming with his three friends, and when he returned 45 minutes later, his friends were nowhere to be seen.

A paddle boarder found one of the missing teens after hearing cries for help. Within 20 minutes a second teen was found.

The two teens were rescued near Station 28.5, near Breach Inlet, according to a firefighter with the Sullivan's Fire Department. One of the teens told emergency officials he tried to help 17-year-old James Williamson, who drowned, but was overtaken by a wave.

Helicopters were later used to locate Williamson.

A memorial was held at Fort Dorchester High School on Thursday for Williamson, who had recently graduated from the school.
