On an oil-stained blacktop beside a Harvey convenience store, someone shot and killed 20-year-old trade student Tommy Lee in his car. Five years later, his parents still have the sedan, two bullet holes rusting in the hood and fender. They also have file folders documenting years of letdown in their pursuit of Tommy’s killer. Sitting around the kitchen table in a suburban split-level, they say Harvey police lied to them, yelled at them and made them feel like a bother. A state police agent who reviewed the case told the Tribune that Harvey’s handling of the investigation was a “travesty.”
