"Local station inspector Pol Maj Yannaphat Malai said that a 45mm automatic firearm, a bullet shell, a glass of vodka, a pair of sunglasses, and a pack of cigarettes were also found near Delacote's body."
It is not a 45mm automatic firearm, the report should've read .45, which is about 11mm caliber. There are no pistols chambered in 45mm caliber, artillery or tank shells perhaps.
