In 1997, Williams was arrested and charged with sexually assaulting and killing Gretta-Morgan’s 20-month-old daughter Quortney. He was eventually sentenced to 48 years in prison, but was released Thursday, the anniversary of Quortney’s death. According to the McHenry County Sheriff's Office, Williams was released Thursday and is registered as a sexual predator with the sheriff's office, with an address in unincorporated Crystal Lake. Officials say they have "proactively" verified all of Williams' information. “I understand the resident’s concerns with Williams’ release into our community. I want to reassure the residents that we proactively and continually verify all of our registered sexual offender’s information to ensure that they comply with the Illinois Sexual Offender Registration Act.”, Sheriff Bill Prim said.
