The second round of sentencings in a Christmastime robbery spree began Thursday as a 19-year-old Brewer man was ordered to spend four years in prison.

Edward Williams pleaded guilty earlier this year to two charges of Class A robbery, springing from a Dec. 13 purse-snatching outside Shaw’s Supermarket and the Dec. 30 robbery of the manager of the Harborside Restaurant in Brewer as he made a nighttime bank deposit.

Justice Eugene Beaulieu ordered concurrent 12-year penalties for Williams, then suspended all but four years and ordered him placed on probation for six years after his prison term. While on probation, he is to submit to searches of his person, home and vehicle; submit to tests for the presence of alcohol or drugs; and work toward obtaining his high-school equivalency diploma.

Williams was one of six youths involved in some of the 10 robberies, most of them at stores and gas stations between Orono and Newburgh. Three were sentenced in May. The two remaining sentencings are scheduled for Friday and for next week. The youths were arrested in a police roundup one weekend in January.

Williams and four others pleaded guilty to the charges before their cases were presented to the grand jury. The last pleaded guilty soon after he was indicted.
