A $1,000 reward fund has been established to go to anyone who can help Montgomery County authorities arrest and indict the man who raped an 8-year-old girl in Silver Spring last year.

George R. Ludington of the Montgomery County Crime Solvers said $500 was contributed by his organization and the rest came from an anonymous donor who had read a story in The Washington Post about the girl and the psychological trauma she has undergone as a result of the rape.

The girl was walking on a path from her home in an apartment complex shortly after 8 a.m. Wednesday, Nov. 21, 1984, to go to her school bus stop, when a man grabbed her from behind and dragged her into a nearby wooded area, police said. They said the man threatened to kill the girl with a knife if she screamed.

A counselor who has worked with the girl in the year since the attack said the girl "doesn't feel safe because the attacker hasn't been caught. It is still fresh in her mind that if the man found her once, he may be able to find her again."

Police said the girl was attacked by a man wearing blue jeans and a white long-sleeve shirt and carrying a pocketknife. They said he was about 20 years old, about 5 feet 5 inches tall and about 130 pounds.

Anyone who wants to contribute to the reward fund or who has information that could help police should call Crime Solvers in Montgomery County at 840-2444, Ludington said. The organization is a privately funded, nonprofit group that provides reward money for police use.
