David Kallenberger, 47, of Lafayette, Indiana, was last seen March 15, 2016, after setting out on his Harley Davidson to visit his sister in Florida. A state trooper encountered him at 3:20 p.m. on Interstate 65 near Franklin, Indiana, where his motorcycle had broken down. Kallenberger told the trooper that help was on the way and that he had contacted his sister to arrange for a friend to assist him.

Later that day the motorcycle was still at the scene but Kallenberger was gone. A voicemail he left for his sister during that period said he felt he was being set up, hinted he had a gun (likely a BB gun), and described a truck backing up near him before the message ended with Oh my God. Despite extensive searches, he has not been heard from since and his family fears foul play. The Indiana State Police continue to seek information.

If anyone was traveling I-65 near Franklin on March 15, 2016, or remembers seeing Kallenberger or his motorcycle, can you share what you saw with investigators?
