Charges against the 28-year-old driver include auto manslaughter, vehicular homicide while under the influence of alcohol and failure to remain at the scene of an accident resulting in death, according to the Baltimore County state's attorney's office, which announced the indictment May 2.
The victim was standing in a lane that had been closed for construction before dawn when a speeding vehicle caromed off a concrete barricade and hit him. The vehicle carried the man more than 100 feet before it crashed into a truck.
The accident occurred despite extensive safety precautions at the work site, including a parked state police car with its emergency lights on several hundred yards before the crash scene, along with message boards, signs and fluorescent barrels along the roadway.
After the accident, the driver drove away, then stopped not far away. Witnesses said the driver got out of the vehicle and appeared to check the damage before driving away.
The driver's silver BMW was found abandoned and with significant body damage a few hours later. Police then contacted the driver, who agreed to cooperate with investigators.
