After serving nine years of a 33-year prison sentence for a 2008 armed robbery involving his own sports memorabilia, former football legend O.J. Simpson pleaded for his freedom Thursday on live television.

Simpson, now 70 years old, became an infamous household name after being implicated in the 1994 murders of his ex-wife, Nicole Brown Simpson, and her friend Ron Goldman. He was acquitted in the highly-publicized trial that followed.

Simpson asked Nevada parole officials to release him in October, when he will have served the minimum nine years.
