A Bucks County judge has given a man 7 to 15 years in state prison for a robbery spree last summer. He must also get drug and alcohol treatment.  25-year-old Edward Schreiner of Northampton pleaded guilty to armed robbery and related offenses.  He admitted showing a handgun and robbing a Game Stop in Doylestown Township, Pier One Imports in Montgomery Township, Tantopia Tanning Center in New Britain Township and Yum-Yum Donuts and Manhattan Bagels in Warminster.  Store surveillance camera pictures led to his arrest.  His lawyer says Schreiner is working toward getting his life back together.
