A man believed to be a brother of Reed has been missing since Friday afternoon, when he reportedly jumped into the Mississippi River near St. Rose, La., to evade police.
Karen Reed, the mother of Ed and Brian Reed, said investigators in Louisiana found shoes and a jacket belonging to Brian Reed, 28.
The Ravens' organization is supporting Reed and remains in contact with him and his family.
The Ravens departed Baltimore/Washington International airport at 2 p.m. ET Saturday, and Reed was on the team's charter, according to team sources.
Sgt. Dwayne LaGrange of the St. Charles Parish (La.) Sheriff's Office said authorities were unable to identify the man who jumped in the river. He said the man had jumped into the river around 10 a.m. Friday when a deputy told him to put his hands behind his back.
LaGrange said the deputy had spotted the man with a parked car that matched the description of a stolen vehicle.
Authorities have called off the search for the missing man.
