• A man killed six people and himself at a birthday party in Colorado Springs, Colorado.
• Names have not been released, but police said one of the victims was the shooter's ex-girlfriend.
• The mass shooting comes less than two months after ten people were killed at a Colorado supermarket.

A man opened fire at a birthday party in Colorado Springs, Colorado, killing six people, including his former girlfriend, and himself, according to police.

The shooting occurred after midnight on Sunday at a mobile home in the 2800 block of Preakness Way where the party was taking place for one of the victims. Police received a call about a shooting at 12:18 a.m., and when they arrived to the scene they found six people dead. One man with serious injuries was transferred to a hospital where he later died.

Colorado Springs Police Department said friends, family, and children were at the party, when the suspect, an ex-boyfriend of one of the people in attendance, entered the trailer and began shooting. The gunman did not injure the children, who are now with relatives as police continue their investigation.

"Today we find ourselves mourning the loss of lives and praying solemnly for those who were injured and those who lost family members in a senseless act of violence on Sunday morning," Colorado Springs Mayor John Suthers said in a statement. "We think too of the emergency personnel who responded to a horrific scene and we keep them in our prayers today."

Names of the victims or the suspect have not yet been released.

Colorado Springs is the second-biggest city in Colorado, after Denver, and has a population of about 465,000.

The mass shooting comes less than two months after another mass shooting in the state. On March 22, a man opened fire at a King Soopers grocery store in Boulder, Colorado, killing ten people.

In 2015, two other mass shootings occurred in Colorado Springs when a man randomly shot and killed three people on Halloween. A month later, another man opened fire on a Planned Parenthood clinic and killed three people, including one police officer.
