Federal authorities plan to file a sex-offender charge against a 78-year-old man who was recently acquitted of killing a blind woman in upstate New York in 1972.

A state prosecutor revealed in court Monday that Willie James Kimble will be arraigned in U.S. District Court next week on a charge of failing to register as a sex offender in Florida. If convicted, he could draw up to 10 years in prison.

Kimble was acquitted March 10 of bludgeoning to death Annie Mae Cray at her home in Rochester on Oct. 29, 1972.

After his trial, the twice-convicted sexual predator was ordered held on state charges he violated his sexual-offender status by skipping town in 2009 while the murder was being re-examined. Police tracked down Kimble in his native Sarasota, Fla.
