He had been serving in Iraq for almost a year and was due to return home in March. Army Specialist Golby joined the service one year after graduating from the Richland Township High School in 1995. Before his tour in Iraq, he completed missions in Kosovo, Afghanistan, and Africa ...visiting 37 countries in all. His family says he died doing what he loved.
