The Boston Fire Department and State Police report two men jumped into the Charles River from the Mass. Ave. bridge around 11 p.m. last night.
Boston firefighters and state troopers arrived at the middle of the bridge in time to spot one person in the river "barely treading water." In a statement, State Police say:
State Police Lieutenant Paul Maloney and Trooper John Dwyer arrived on scene and heard screams coming from the water. Trooper Dwyer threw his cruiser's spare tire into the water to assist one of the men, whom they could hear, but not see.
After several attempts, one of the men grabbed onto the tire, and held onto it until a firefighter from Ladder 15 in a survival suit was lowered into the river. The firefighter then held him until a State Police boat arrived to take them to shore.
The man, a 27-year-old Dorchester resident, spent 20 minutes in the water and was taken to Brigham and Women's Hospital, State Police said.
Around 12:15, divers from the Cambridge Fire Department recovered the body of the other man, a 28-year-old from Hyde Park.
NECN reports the men drove onto the bridge, then got out of their car before winding up in the river.
