Police were watching a suspicious vehicle in the side parking lot of the Red Roof Inn at 200 Worcester-Providence Turnpike when one of the detectives walked over and began making conversation with the person inside, Sutton police said in a Facebook post.
As they spoke, the detective scanned the car's interior until his eyes landed on an M190 U.S. Army Rocket Launcher, authorities said. That's a conversation killer.
Harvey Johnson Jr., of Spencer, was arrested and charged with possession of a Class B substance (crack) and possession of an incendiary device, police said.
Sutton police called in Alcohol, Tobacco, and Firearms agents to take custody of the rocket launcher.
