On the morning of August 21, 1996, Dennis Appleby left his Moline, Illinois home to head to work, leaving behind his 11 year old daughter, Trudy, to spend the summer day at home. Around 9:30am, a neighbor saw Trudy with a man who appeared to be in his 20’s, with dark curly hair, wearing a baseball cap. The unidentified man was driving a silver or gray four door sedan. Dennis came home from work that evening and was surprised to find his daughter wasn’t home. He called his neighbors and some of Trudy’s friends but she wasn’t with any of them. That is when Dennis called the police to report Trudy missing. Trudy’s case went unsolved for more than 20 years but now, investigators believe they know who is responsible for Trudy’s disappearance.If you have any information regarding the disappearance of Trudy Appleby, please call the Moline Police Department at 309-524-2140.See Privacy Policy at https://art19.com/privacy and California Privacy Notice at https://art19.com/privacy#do-not-sell-my-info.
