Simpson, 65, is expected to testify sometime this week. The public might be surprised at his appearance after four years in prison.
"He's slow, " said close friend Jim Barnett, who has visited the former football star several times. "Last time I saw him, he had gotten quite heavy."
Simpson says his trial attorney never told him that the prosecutors had offered a plea bargain. He also said in a sworn statement that the same lawyer "advised me that I was within my legal rights" to attempt the memorabilia sting that landed him in this mess.
Sentenced to a maximum of 33 years in prison, Simpson will be 70 before being eligible for parole.
