Ten people were in the home during the shooting. Three women, a man and an 8-year-old boy were killed, Capers said.

The suspect was the victims’ neighbor and went to their home Friday night after they asked him to stop shooting an AR-15-style rifle in his front yard because of the noise, Capers said.

Oropeza frequently shot the rifle in his yard, Capers said, and allegedly became angry when the neighbors said their baby was trying to sleep around or after 11 p.m. Authorities saw video footage of Oropeza walking up to the victims’ front door before going inside.

“The neighbors walked over and said … ‘Hey man, can you not do that, we’ve got an infant in here trying to sleep’ or whatever,” Capers said. “They went back in their house and then we have a video of him walking up their driveway with his AR-15.”

Law enforcement officers responded to the Cleveland home after a report of “harassment” about 11:30 p.m. Friday, Capers told reporters early Saturday morning.
