The driver of a car that killed seven persons last August when it plowed into a crowd at a Southeast bus stop was indicted by a D.C. Superior Court grand jury yesterday on seven counts of second-degree murder while armed.

The indictment accuses Robert L. Williams, 41, of using his vehicle as a weapon without regard for the life and safety of others.

Williams faces a maximum sentence of life on each of the charges if convicted. The grand jury also charged him with assault with a dangerous weapon.

Four members of one family were among those killed when Williams' car, traveling east in the 200 block of M Street, struck the median strip, jumped a curb and plowed into the crowd standing near a brick wall outside the Washington Navy Yard.

Rescue personnel described it as one of the worst accidents they had ever seen.

At the time, Williams had been on parole for about six weeks from prison in Virginia, where he had served part of a 20-year sentence for bank robbery.

Police said Williams' blood-alcohol level was measured at 0.10 percent the night of the accident. He faces lesser charges of driving while intoxicated and reckless driving.

Families of some of the victims have since filed suit against Metro, claiming the transit company was negligent when it placed the bus stop near the wall.
