Richard F. Newcomer, a 64-year-old superintendent with Gilbane Building Co., was fatally shot on September 6, 2018, in the lobby of the Fifth Third Center in Cincinnati during a mass shooting. The attack left three people dead, including Newcomer, and injured two others. The shooter, identified as Omar Santa Perez, was described as an Ohio man dressed in business casual and carrying a briefcase before opening fire. Police engaged the gunman in a shootout; the shooter died at the scene.

Officials said Perez had no known connection to the victims and appeared to have acted randomly. Mayor John Cranley highlighted Newcomer’s work in the city’s construction industry and offered condolences to the family. Newcomer is remembered by his family as a loving husband, father, and grandfather.

Did anyone who worked with Newcomer at Gilbane or who was in the Fifth Third Center that day see anything that helps explain how the shooter gained access to the lobby?
