Two 19-year-old Washington men were charged yesterday in the shooting of Steve Adams, a 27-year-old cabdriver who was found slumped over the wheel of his cab in the 1200 block of Southern Ave.

The shooting followed the murders of two other cabdrivers last Tuesday and Wednesday.

Police identified the suspects as Anthony Rush Bigelow of 1317 Emerald St. NE. and Marquette Henderson, of 1234 Southern Ave. SE. Both were charged with asault with intent to kill. They were arrested at their homes.

Adams, a Liberty Cab driver who lives at 1104 Massachusetts Ave. SE., was shot with a .32 caliber revolver in the back of the head, just behind his right ear, police said. He was in stable condition yesterday at George Washington University Hospital, a spokesman said.

According to police, Adams was alert and able to describe the incident immediately after he was found.

Police said Adams picked up the two men, who had just come from a disco near 12th Street and New York Avenue NW. The men asked Adams to drive them to the Southern Gardens apartments in the 1200 block of Southern Avenue.

When they arrived, one of the men shot Adams in the back of the head, police said. Adams temporarily blacked out, his foot slipped off the brake and onto the accelerator, causing the cab to strike nine cars in the parking lot, police said. Bigelow was taken to D.C. General Hospital for treatment of a back injury after his arrest, police said. He was being held there under police guard.

D.C. Superior Court Judge Nicholas Nunzio ordered Henderson held in the D.C. jail without bond until he is arraigned Friday.

of the cab helped lead police to Bigelow and Henderson, a detective said yesterday.

Police said they are still seeking suspects in last week's fatal shooting of Lloyd D. Jones, 31, an Autorama Cab driver, and in the fatal stabbing of David Hughes Jr., 50, a Meteor Cab driver.
