The FBI is investigating the alleged beating death last year of Charles Givens — a disabled inmate at Virginia's Marion Correctional Treatment Center. NPR first wrote about this case last month in a story that detailed allegations of abuse Givens may have suffered while incarcerated at Marion.

In an email to his sister, Kymberly Hobbs, confirming the ongoing investigation, the FBI said it has identified Givens "as a possible victim of a crime."
