this doesn't surprise ernestine bibbs, who, like the morgans, paid pickering for a faulty heating systems intentional, and that's what bothers me. he was intentionally going out trying to take advantage of people. >> bibbs won a judgment against pickering in small claims court, but he never paid her a dime. >> he's still running around out there, and i'm really surprised that the state can't catch him. >> so why can't contractors like pickering be stopped? states view homeowner complaints as strictly a civil matter. in order to stop pickering board investigators must build a case by catching him in the act. on this day, villucci makes nabbing pickering priority number one. >> we just drove by roy pickering's house. i did see his work truck in the driveway, so we're going to go get another look. set up a location so we can watch him. >> villucci and three investigators in separate cars have staked out both of pickering's houses. they hope to catch him working without a license. >> you see the blue truck leave, if it's a big blue truck, that's the one we want. it's going to have pickering
