Crystal Ann White, 20, the manager of a Washington dry cleaning establishment and a 1979 graduate of Rockville Senior High School, died Saturday at D.C. General Hospital of injuries she suffered in an car accident earlier that day.

D.C. police said Miss White was the passenger in a car driven by Mark Prout, 20, of Washington, which collided with a van about 1:30 a.m. in the 4400 block of South Dakota Avenue. Police said Prout was admitted to the Medstar unit at the Washington Hospital Center and later charged with driving on the wrong side of the road.

Miss White, who was thrown from the car during the collision, struck her head on the curb and died at D.C. General Hospital, police said. They also said the driver of the van was not injured.

Miss White was born in Washington and lived in Takoma Park before moving to Rockville six years ago. After graduating from high school, she attended Montgomery Junior College. For the last year she had been the manager of E&G Dry Cleaners on Kennedy Street NW.

Survivors include her parents, Gertrude and Edward E. White, both of Rockville, and a grandfather, Harry L. Jones, and a stepgrandfather, Richard Ruffin, both of Washington.
