WASHINGTON, Pa. (AP) – Hundreds of people gathered to remember a western Pennsylvania graduate student killed in a mass shooting in an Ohio nightclub district last weekend. Mourners from all stages of the life of 25-year-old Nicholas Cumer filled every seat in Saturday’s service and lined the hallways of a Washington, Pennsylvania funeral home. Pastor Brian Greenleaf said Cumer “had a heart bigger than his chest.” He was among nine people killed early last Sunday by a gunman who was then killed by police shortly after he opened fire at a bar in Dayton, Ohio. Cumer was a graduate student in the master of cancer care program at Saint Francis University in Loretto, Pennsylvania. He was in Dayton as part of his internship with the Maple Tree Cancer Alliance.
