Officers with the Colorado Springs Police Department responded to a report of a shooting at approximately 12:18 a.m. Saturday evening at the 2800 block of Preakness Way in Canterbury Mobile Home Park.
Upon arrival at the trailer, responding officers discovered six deceased adults and one man with serious injuries. The man was transported to a local hospital, where he later succumbed to his injuries.
The suspected shooter was the boyfriend of a female victim at the party attended by friends, family and children. He walked inside and began shooting before killing himself, police said. The children at the trailer were uninjured by the suspect and are now with relatives.
Police have not released the names of the victims or the suspect and an investigation is underway to determine a motive.
Colorado Springs Police Chief Vince Niski said in a statement that "words fall short to describe the tragedy that took place this morning."
"As the chief of police, as a husband, as a father, as a grandfather, as a member of this community, my heart breaks for the families who have lost someone they love and for the children who have lost their parents," Vinski said, "From the officers who responded to the shooting to the investigators still on scene, we are all left incredibly shaken."
"This is something you hope never happens in your own community, in the place that you call home. When these types of unspeakable acts happen, there is nothing that can be done to fully rebuild what was lost or replace those who are no longer with us," Niski added. "My vow to this community and to the families who have lost someone today, is that this department will do everything we can to find you the answers you deserve and be here for you with an unwavering support."
Colorado Gov. Jared Polis called the incident "devastating, especially as many of us are spending the day celebrating the women in our lives who have made us the people we are today."
"Multiple lives were taken today by this terrible act of violence. Families torn apart, and at a birthday party no less," Polis continued. "My deepest condolences and prayers are with the victims, their families, and everyone else impacted by this tragedy."
