Yes, OJ Simpson is in the medium-security Lovelock Correctional Center in Nevada. (Simpson was acquitted in the June 12, 1994 stabbing deaths of his ex-wife and her friend.)
In December, 2008 he was sentenced to a prison term of 33 years without the possibility of parole for 9 years, related to an armed robbery in 2007 (he was charged with other crimes as well, including kidnapping). This was in contrast to the potential life sentence he was facing for this offense that took place at the Palace Station hotel.
He will be up for parole in 2017 at the age of 70. If he remains incarcerated for his full sentence it means he'll be 94 years old by the time he's released.
Walraven.org offers a collection of transcripts from the infamous Simpson trial held in 1995.
OJ is currently waiting for the Nevada state Supreme Court to rule on his appeal for early release from prison. Get the scoop from CBS News.
