Ten people killed in shooting at Colorado supermarket

Police say 10 people have been killed in a shooting at a Colorado supermarket.

Boulder Police Chief Maris Herold said Monday night that a lone suspect is in custody and is getting medical treatment.

Police refuse to speculate on a motive, saying the investigation has just begun.

One of the victims has been identified as 51-year-old Eric Talley, a member of the Boulder police department since 2010.

The identities of the other nine victims were not immediately disclosed as police were still notifying their family members.

The attack was the seventh mass killing in the U.S. this year.
