LULING, La. — A body pulled from the Mississippi River has been tentatively identified as the brother of Baltimore Ravens safety Ed Reed, authorities said Wednesday at a news conference attended by the NFL star.

St. Charles Parish Sheriff Greg Champagne said tattoos on the body recovered late Tuesday appear to match those belonging to 28-year-old Brian Reed, who jumped into the river after an encounter with a sheriff’s deputy. An autopsy was planned for Thursday.

Ed Reed said his brother was driving another brother’s car on Jan. 7 and was suffering “mental issues” that day. The family reported the car as being driven without authorization to “basically slow my brother down and just bring him in, bring him home,” Reed added.

“Unfortunately, he thought otherwise,” he said of his brother.
