(real name Russell Jones) will have his criminal record assessed and will undergo a psychological evaluation. Officials from the Chino, California facility will then send their recommendation back to the judge, who will place O.D.B. back on probation or sentence him to serve prison time. The rapper is due back in court on June 23. O.D.B. has remained behind bars since January, when he was kicked out of the Impact House drug treatment facility.
