Twenty years after rape, offender back on the run

U.S. marshals are searching for a violent sex offender once convicted of raping his adoptive mother, and authorities are seeking the public’s help in tracking him down.

In 1985, at age 16, Robert Joseph Williams raped, sodomized and robbed the woman who adopted him, police said. Police tracked him down in California, authorities said. Williams served 20 years of a 35-year prison sentence and was released on supervised parole in 2006. But police said he wasn’t able to stay out of trouble, and a warrant was issued by the Loudoun County Sheriff’s Office on possession of drugs with intent to distribute.

Williams is also wanted by Virginia State Police for failing to register as a sex offender and by the Virginia corrections department for violating his parole, officials said.

“Williams is an extremely dangerous individual. He did 20 years in prison and still will not comply with the rules and conditions of his early release,” said Rob Fernandez, commander of the Capital Area Regional Fugitive Task Force. “We need the community’s help in locating him. Any information that can lead our investigators to him is vital.”

Williams, 40, has a lengthy history of violence and mental issues. He is described as a white male, 5-foot-10, 270 pounds, with brown hair and brown eyes. He has a scar on his left arm. His last known residences were in Annandale and Fairfax.

Anyone with information on Williams’ whereabouts can call the U.S. Marshals Service at 800-336-0102.

The Capital Area Regional Fugitive Task Force, run by the U.S. Marshals Service, is comprised of 30 federal, state and local agencies from Baltimore to Norfolk. The unit has captured more than 29,000 wanted fugitives since its creation in 2004.
