The assassination of Dr. Martin Luther King, Jr. Was on April 4, 1968. Within minutes after the shooting of Dr. Martin Luther King, Jr., a local police officer discovered a Remington 30-06 rifle, several unused bullets, and other effects that belonged to James Earl Ray, wrapped inside a blanket, outside Canipe's Amusement store.

Edit the model pictured is the Remington Model 760s in .308 caliber. I wasn't disagreeing with op just pasted a quick search I did.
