Traffic accidents on Christmas Eve and Christmas Day marred the holiday in the Washington area.

In Maryland, there were two traffic fatalities, one on Christmas Eve and the other Christmas morning, according to police.

Harry Lee Mitchell, 69, of Bowie was killed about 11:15 p.m. Tuesday when the small car he was driving without its headlights on crossed over the center lane of Superior Lane in Bowie and crashed into another car.

No one in the other car was injured.

The other fatality occurred early yesterday after a car driven by Troy Lee Still, 19, hit a curb at Cremen and Saint Barnabas roads in Temple Hills. Still lost control of his 1972 Buick and struck a street lamp pole, police said.

Still, of 4712 Beauford Rd., Morningside, was trapped in his car for about an hour and then taken to Prince George's General Hospital, where he died at 4:15 a.m., police said. Officials could not say whether the victim in either accident was wearing a seat belt.

In Virginia, meanwhile, a Hyattsville woman was critically injured when the truck in which she was riding early Christmas morning struck a legally parked tractor-trailer on Old Richmond Highway in Alexandria.

Rosalinn A. Holt, 28, of 1810 Chillum Rd., was first taken to Mount Vernon Hospital before being transferred by helicopter to the Washington Hospital Center, police said. She remained in critical condition in the intensive care unit there late yesterday.

Police said Holt's head struck the windshield of the half-ton pickup driven by John D. Bynum, 52, of 110 Anacostia Rd. SE.

Police said Bynum's truck ran off the side of the road at Old Richmond Highway and Cameron Run Terrace about 1 a.m. Bynum was treated at Mount Vernon Hospital and released. But police said he has been charged with failure to pay full attention. Neither Bynum nor Holt was wearing a seat belt, police said.
