The plea/trial setting for a former Carrollton Police Officer has been scheduled for 10:00 a.m. Tuesday.  The charges against Robert Baker, 34, include two counts of possession of a controlled substance and two counts of unlawful use of drug paraphernalia.  He was arrested in March 2012 after Marshall police uncovered a synthetic stimulant, a baggie with residue, and other items in Bakert’s vehicle.
