Prouse pleaded guilty by way of information, as opposed to a grand jury indictment, to second-degree robbery. In exchange for his plea, Akers said prosecutors will drop two other robbery cases against him, including one involving his own parents.
He faces a possible sentence of five to 18 years in prison when he returns to court in December.
He was expected to plead guilty Wednesday, but changed his mind at the last minute. He told the judge he changed his mind again and decided to accept the plea agreement.
"I was scared yesterday," he told King when asked to explain. "I thought I could get a lower sentence. It's still a big sentence for what it is but I got to take what it is."
Gail Michelson, Prouse's public defense attorney, indicated that she will request that he be sent to the Anthony Center for Youthful Offenders.
King questioned Prouse's rush to plead guilty, but said he understood the evidence against him was "substantial."
King said, "It would be difficult to challenge his own mother, successfully that is."
