The U.S. Coast Guard suspended its search Tuesday morning for a possible person in the water near the Charleston City Marina.

According to Petty Officer 3rd Class Anthony Soto, an overnight search failed to produce results and no sign of distress was found. No one was reported missing or overdue to the Coast Guard, he said.

Coast Guard crews have suspended their search around 8:20 a.m. pending any new developments, Soto said.

A security guard at the marina reported hearing a cry for help around 2:45 a.m., according to officials with Coast Guard Sector Charleston.

The Coast Guard launched rescue crews to search a four-mile stretch of the Ashley River. An Urgent Marine Information Broadcast was also issued, officials said.

A helicopter crew from Air Facility Charleston assisted in the search, along with rescue crews from the Charleston County Sheriff's Office and Charleston firefighters, officials said.
