The brother of Baltimore Ravens star safety Ed Reed is missing after escaping police pursuit by jumping into the Mississippi River in Louisiana, multiple media outlets have reported.

According to New Orleans station WWL-TV, St. Charles Parish sheriff’s officers were pursuing 29-year-old Brian Reed in St. Rose, La., on Jan. 7 when he was last seen jumping into the river at about 10 a.m. He apparently swam underwater and disappeared.

“The suspect jumped into the river, went about 15 feet according to the deputy,” Sgt. Dwayne LaGrange, a spokesman for the St. Charles Parish Sheriff’s Office, told the TV station. “At some particular point they said he did witness hands and head come up and go under the water and never resurface again.”

Because police have not yet found and identified the suspect, they cannot yet confirm that it was indeed Ed Reed’s brother being pursued. But police was reportedly chasing Brian Reed because his car matched the description of a vehicle reported to have nearly run another vehicle off the road.

His mother, Karen Reed, told The Baltimore Sun that she believes the suspect may be her son and acknowledged that Brian has faced drug and alcohol abuse problems in the past.

But Wendell Sanchez, the oldest of Reed’s five brothers, told the Sun that they had not heard anything from police and there’s a chance the suspect may not be Brian.

“We still have hope that it’s not him,” Sanchez told the newspaper. “There’s a window that he’s OK.”

Sanchez told Sun reporters that he talked with Ed and that there were no current plans for the NFL player to travel to Louisiana. Ed Reed is scheduled to join the Baltimore Ravens for a road playoff matchup against the Kansas City Chiefs on Sunday, Jan. 9.

“We’ve been in contact as an organization,” Ravens head coach John Harbaugh told the Sun. “All I want to say is, our thoughts and prayers are with the Reed family at this difficult time. We’re just praying for them. I love Ed Reed, I know he’s fighting something now and hopefully it’ll turn out OK.”
