COLORADO SPRINGS, COLORADO - A man fatally shot six adults, including his girlfriend, and then himself at a birthday party in Colorado Springs, Colorado, early Sunday, sparing the children who were present, officials said.
"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," a statement released by the Colorado Springs Police Department said.
A motive has yet to be determined.
The massacre took place about 110 km (70 miles) south of Denver and is the latest in a resurgence of mass shootings in the United States after such incidents seemed to recede during the height of coronavirus pandemic restrictions.
Among the incidents this year was one in Boulder, Colorado, where a man has been charged with 10 counts of murder in a shooting spree at a supermarket about 50 km (30 miles) northwest of Denver.
Two other deadly rampages have taken place in Colorado, both in the Denver area: the 1999 shooting at Columbine High School that killed 15 people including the two perpetrators, and the 2012 shooting in a movie theater that killed 12 people and wounded about 70. That gunman is serving a life sentence.
Colorado Springs Police Chief Vince Niski said "my heart breaks for the families" in Sunday's attack and promised to support them.
"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," Niski said in the police statement.
Police said they withheld releasing details of the shooting for several hours "in order to properly and respectfully notify family members of the deceased and ensure support was in place."
The names of the victims will be released later, the statement said.
