Police on Monday are investigating what led a gunman, who they said was the boyfriend of one of the victims, to walk into a crowded birthday party inside a trailer park home in Colorado Springs early Sunday and open fire.
Six adults were killed at the home at the Canterbury Mobile Home Park on the east side of Colorado's second-largest city, and a seventh died at a hospital, authorities said. The shooter was the boyfriend of a female victim at the party attended by friends, family and children, police said.
Authorities didn't release the names of the victims, gunman or disclose a possible motive. Nor did they release any further details on what weapon or weapons were used. Officials were still in the process of identifying the victims, Sandy Wilson of the El Paso County Coroner’s Office said Monday.
