"Upon arrival, officers located six deceased adults and one adult male with serious injuries who was transported to a local hospital where he succumbed to his injuries," the statement read.

The CSPD said that through an initial analysis of evidence and preliminary interviews they believed the mass shooting incident occurred when a birthday party was being held for one of the victims.

The suspect, a boyfriend of one of the female victims, drove to the residence, walked inside and began shooting people at the party before taking his own life.

The children at the scene were not injured by the suspect, police said, noting they were still investigating to determine a motive. More details would be released later.
