As part of a plea agreement 35 year old Adrian Irby avoided a trial by pleading no contest to two counts of possession with intent to deliver amphetamine and one count of felon in possession of a firearm. Three other counts were dismissed and read into the record. A sentencing hearing is scheduled for Friday.
