DALLAS (CBSDFW.COM) – An unarmed security guard was shot and killed early Wednesday outside of a northwest Dallas hotel. The deadly incident happened at about 1:15 a.m. at the Holiday Inn Express & Suites in the 9000 block of Vantage Point Drive, just off of the LBJ Freeway near Greenville Avenue.

Police said that a man came to the hotel but, for some reason, the 72-year-old security guard asked him to leave. The man left, but returned a short time later holding a gun. He fired several shots at the unarmed guard, striking him and killing him at the scene.
