Two teenagers have pleaded guilty to stealing a computer belonging to Robert Blake's (search) attorney that contained vital information in the actor's murder case.

The laptop computer was stolen from M. Gerald Schwartzbach's (search) apartment Dec. 1 while the attorney was preparing for Blake's trial in the death of his wife, Bonny Lee Bakley. The theft delayed opening statements, but police said it had no connection to the trial.

Michael Washington Jr., 19, pleaded guilty Tuesday to two counts of residential burglary and was sentenced to two years in prison. Koi Burton, 18, pleaded guilty to a single residential burglary charge. He was scheduled to be sentenced May 23.

The computer and other items were recovered at a Los Angeles (search) pawn shop the same day as the theft. Blake was acquitted in March in the May 2001 murder of Bakley.
