"I know the court has made orders for accommodations ahead of time, that any transportation is going to be medically complaint, that he has an adequate bed," said Chief Assistant District Attorney Robert Trudgen. "I know efforts are at least being made."

Disability rights advocates, however, paint a different picture of the California state prison system. The California Department of Corrections and Rehabilitation's medical system has been under federal monitoring since 2006, when a federal judge ruled it unconstitutionally inadequate and in violation of the 8th Amendment.

According to the ACLU, California state prisons are overcrowded, at 136.6 percent capacity. Quality of life for inmates with disabilities varies widely from facility to facility, and they often spend lengthy periods of time in highly restrictive reception centers—where they don't have phone privileges and can only interact with visitors through glass—while the state assesses their medical needs and places them in an adequate facility.

"We are concerned how the state system would treat him because the CDCR is under a mandate, and are being monitored for not treating the prisoners well," says Williams' lawyer, Joanne Biernacki. "I've read reports on prisoners not doing well in the state prison system. The last thing I want is for him to go in and get sicker."

"We were hoping for something better," says Williams' close collaborator Dontrell Mayfield, a.k.a. 4Rax of the production duo the Mekanix. "We talked to him yesterday and what was really the focal point was, 'I’m ready to put this behind me.' The clock is ticking and we gon’ pray for him and wait for him to come on out."

Prior to starting his sentence, Williams worked on music and a documentary set to be released sometime during his term. As he explained in January, "It got me doing a lot of recording right now, so while I'm gone I can be dropping music to take care of my family."
