When visitors leave Just-In-Time Recreation, a 22-lane bowling alley in Lewiston, Maine, they are encouraged to come back by a cheery sign in art deco font: “Thanks for playing. See you again in your spare time!”
Surveillance video from Wednesday evening captured a man with his back to that door as he entered the alley. He was carrying a black AR-15-style firearm fitted with a powerful riflescope for accurate targeting.
