In late summer 1985 Mishawaka, Indiana, a local coin shop manager was found fatally shot in what investigators first treated as a robbery. On August 28, 41-year-old Thomas Lionel Rohr was discovered dead inside the coin shop he managed; the death was ultimately ruled a homicide by gunshot.

Investigators later connected Rohr’s killing to a pattern of violent robberies and murders targeting coin and antique dealers in multiple states. The attacker, dubbed the Coin Shop Killer, reportedly took time to learn shop layouts and owners before striking and frequently killed victims with gunshot wounds to the head. On August 16, 1990, Charles T. Sinclair was arrested in Alaska and authorities said items seized from him — including maps, tools for false identifications, and coins — tied him to a string of such murders that included Rohr.

Did anyone in Mishawaka in 1985 notice a stranger spending time at local coin or antique shops who might help explain how this case unfolded?
