Two men remain hospitalized in critical condition tonight after jumping from the Tobin Bridge into the Mystic River this evening.

Massachusetts State Police assigned to Troop F, members of the State Police Marine Section, and State Police detectives assigned to Suffolk County District Attorney Daniel F. Conley’s office responded to the scene shortly before 5:30 for reports of two men jumping from the upper deck of the Tobin Bridge. Troopers recovered the duo, a 35-year-old Revere man and a 31-year-old man from Bedford, New Hampshire, from the river and transported both to a nearby U.S. Coast Guard base for transfer to Massachusetts General Hospital. The men suffered serious injuries in the fall and were unable to speak to investigators.

State troopers closed the rightmost inbound lane of the upper deck, where a car belonging to a Bedford relative was found. Traffic was slowed but not stopped during the response. Witness statements and additional evidence from the scene suggests that the men jumped in a shared suicide bid, but motive and execution remain under investigation by State Police detectives assigned to Conley’s office.

Criminal complaints have not been sought by authorities at this time.
