Authorities called off the search last night for a 48-year-old West Baltimore man thought to have jumped from the Bay Bridge earlier in the day.
Crews from the Coast Guard, Maryland Natural Resources Police, and state and Annapolis police searched the Chesapeake Bay until nightfall but were unable to locate the man, whose name was not released.
The man's car was discovered about 4 a.m. parked in the span's westbound lanes about a mile west of Kent Island with the motor running. A passing motorist noticed the car and called Maryland Transportation Authority police on a citizens' band radio.
Police found blood inside and outside the car, a knife, the man's wallet and keys. Lori Vidil, Transportation Authority police spokeswoman, said authorities are not sure what happened to the man.
A Coast Guard spokesman said the rescue units searched an area 4 miles north and 4 miles south of the Bay Bridge.
