Colorado gunman killed six at party ‘as he was not invited’

Colorado officials say the gunman who killed six people at a birthday party at the weekend was upset that he had not been invited.

Police say Teodoro Macias, 28, fatally shot his girlfriend, Sandra Ibarra-Perez, 28, and five relatives before turning the gun on himself.

The attack unfolded at the Canterbury Mobile Home Park in Colorado Springs early on Sunday.

The party was for three relatives, two of whom died.

The attack came less than two months after a mass shooting that left 11 dead at a grocery store in the north-central Colorado city of Boulder.

Police say the Colorado Springs gunman had a “conflict” with the targeted family at a separate event about a week earlier, and was a jealous boyfriend.

“At the corner of this horrendous act is domestic violence,” the Colorado Springs Police Chief Vince Niski told a news conference on Tuesday.

He added: “When he [Macias] wasn’t invited to a family gathering, the suspect responded by opening fire.”

He said the killer had “displayed power and control issues”, and had been in a relationship with his girlfriend for about a year. He had no criminal record.

Three teenagers left the party to get an item from a neighbour shortly before the shooting unfolded and returned to the trailer after the attack, police Lt Joe Frabbiele told a news conference.

Three children, aged two, five and 11, witnessed the shooting, and were not physically harmed, said police. Seventeen bullet casings were found in the mobile home.
