A Glen Burnie man pleaded guilty on Tuesday to stealing over 2,000 aluminum carts from the U.S. Postal Service. Roland Michael Muir, 57, admitted in his plea agreement, entered in U.S. District Court in Baltimore, that he and another man used his employer’s truck and then a rental truck to take the mail carts from USPS bulk mail centers in Capitol Heights from 2010 to 2014. Muir worked for a private mailer company in Baltimore. Muir spray painted over the USPS markings and sold the carts to recyclers, making over $323,000. The Postal Service’s cost to replace the stolen carts is nearly $2.9 million. Muir faces a maximum sentence of five years in prison for the conspiracy and 10 years in prison for the theft charge. Co-defendant Aaron Kevin Howard, 52, of Brooklyn, has pleaded not guilty.
