Chapman was arrested last Sept. 19 for allegedly shoplifting more than $15,000 worth of merchandise from an Apple store in Scottsdale and then selling the items at a pawn shop.
Prosecutors say Chapman pleaded guilty last week to four felony theft charges, which could be reduced to misdemeanors at his Sept. 25 sentencing hearing.
The 47-year-old Chapman has agreed to pay full restitution and serve 750 hours of community service.
