A 56-year-old D.C. cabdriver was found shot to death in his cab yesterday on a parking lot in Kenilworth Park, D.C. police reported.

Police identified the victim as Joe Willie Ollie, a driver with the Yellow Cab Co., who lived at 4660 Martin Luther King Ave. SW. Homicide investigators said he had been shot numerous times, apparently from behind, shortly before his body was discovered about 3:30 p.m.

Investigators said Ollie's wallet was missing and called robbery the apparent motive for the shooting. They said they had not been able to determine if Ollie had picked up a fare prior to the shooting or what took him to the park in far Northeast Washington.

Last Thursday night Timothy A. Jones, a self-employed D.C. cabdriver, was shot in the head and critically wounded, apparently after a dispute with two passengers at Stanton and Dunbar roads SE. He remains in critical condition at Greater Southeast Community Hospital.

In January, two D.C. cabbies were slain in separte shootings in suburban Maryland after picking up fares at Georgia and Florida avenues NW about 12 hours apart. Two District men have been charged with murder and robbery in both slayings.

Four cabdrivers were slain in the District last year, at least three of them during robberies, leading to demands from city cabbies for intensified police investigations. One of those cases has since been closed with an arrest, police said.
