On March 11, 1997, 25-year-old James Isom was working at a Comerica Bank branch in Detroit when a gunman entered and opened fire. The shooter, identified as 21-year-old Allen Lane Griffin Jr., carried a 12-gauge pump-action shotgun and killed three people during the rampage, including Isom, who was fatally shot in the head while people lay on the floor. The bank manager, Stanley Pijanowski, was also killed in the back office; two other people were wounded. The shooter left the building, took a customer hostage, and was ultimately killed by police.

Isom’s estate later sued Comerica and the bank’s security company, alleging the bank knew Griffin posed a threat because of his relationship with the branch manager. A court ruled for the defendants, finding insufficient evidence that the bank knew of the specific danger that occurred. Does anyone have additional details about Isom’s life or the Comerica branch that could help shed light on this case?
