A two-vehicle crash on the Baltimore Beltway that snarled traffic for nearly two hours yesterday might have been caused by a driver trying to commit suicide, Maryland State Police said.

Samuel Krasin, 28, of Eastpoint pulled his 1995 GMC pickup truck to the shoulder of Interstate 695 near Harford Road about 1:20 p.m. to use his phone, said Sgt. Steve Seipp. A 1994 Ford station wagon hit his vehicle from behind, pushing the truck into the road, Seipp said.

The station wagon driver, identified only as a 47-year-old Rossville man, told officers that he was trying to kill himself, police said. He was in serious condition at Maryland Shock Trauma Center, police said. Krasin was taken to Johns Hopkins Bayview Medical Center with nonlife-threatening injuries, said Seipp.
