A high-speed police auto chase disrupted evening rush hour traffic yesterday as two robbery suspects were pursued from downtown Washington over the 11th Street Bridge, along I-295 and the Beltway into Fairfax County, police said.

Five private cars, three Fairfax County police cars and one D.C. police car were damaged during the chase, which began about 6:10 p.m. at 4th and K streets NW and ended about 40 minutes later at Braddock and Backlick Roads in Fairfax County, police said. Two D.C. policemen suffered minor injuries when their car crashed, but no other injuries were reported.

Fairfax police said two suspects in the incident, Eddie L. Snavely, 19, and Karen Emory Schaefer, 18, both of 6811 Collridge Rd., Camp Springs, were arrested after their car was forced off the road into an embankment at Braddock and Backlick Roads.

Police said the chase began after the couple drove away from a policeman who had stopped them as possible suspects in a $36 robbery of a man minutes earlier.

Fairfax police said Snavely has been charged with reckless driving to elude arrest and two counts of hit and run. Police said both Schaefer and Snavely were also charged as fugitives from robbery charges in the District.
