The long arm of the law has permanently broken up that old gang of Kingwood High School convenience-store banditas whose rampage for cash and cigarettes earned them face time on such national news shows as 20-20 and 48 Hours. The trio most involved in the series of five robberies -- Krystal Maddox, Lisa Warzeka and Katie Dunn -- took their chances with jury trials and each drew seven-year tickets to prison. Michelle Morneau, the girl with the smallest role in the crime spree and the one who cooperated with police, pled out for a ten-year probation, a stint in boot camp and 2,000 hours of community service. Morneau will spend part of that community time at the Kingwood Public Library, where she will no doubt serve as a poster girl warning the bored, overaffluent teens of that bedroom community that some walks on the wild side are not worth the price.
