Moreira was barricaded inside a home on St. Francis Circle after a 911 call about a person holding someone else at knifepoint, police said at the time. The person escaped, but when officers arrived, at the home, Moreira allegedly opened fire on a SWAT vehicle and periodically shot near the officers who’d circled the home.
State police eventually decided to send in three robots, including Roscoe, to find where in the building Moreira was holed up. Roscoe cleared the top two floors of the building, then discovered him, holding a rifle, in the basement, police said.
He knocked the robot dog down, then started to walk up the stairs, but, when Roscoe righted itself and started following him up the stairs, he knocked the dog over again, then shot it three times. Its pilot lost communication with the dog.
