On June 13, 1996, Maribeth Munn, 53, was one of four people killed during an armed robbery at a firefighters union hall in Tucson, Arizona. Also in the hall that night were bartender Carol Lynn Noel, 50, and a couple, Arthur Taco Bell, 54, and Judy Bell, 46. Two armed men entered, held the patrons at gunpoint and took about $1,300 from the cash register. The victims were later found shot to death; reports say they were forced to rest their heads on the bar before being shot.

The scene was discovered that evening by Munn’s partner, Nathan Alicata. Investigators linked two suspects to the robbery and the killings, and both were prosecuted in connection with this case and another double homicide that occurred two weeks earlier at a smoke shop.

Did anyone who knew Maribeth, the other victims, or who was in that area on June 13, 1996, ever notice anything unusual that night?
