In Colorado, a gunman went on a shooting spree in several locations around Denver Monday, killing five people and wounding two others — including a police officer — before he was shot dead by police. Witnesses to one of the shootings described a chaotic scene as they hid from gunfire in the storeroom of a cellphone store.

Anne Wilson: “There was probably maybe like seven or eight gunshots and then like another set of maybe five more. … Scary. It’s scary that this is what goes on nowadays. It’s not an uncommon event for there to be public shootings. It’s sad. It’s scary.”

The Gun Violence Archive has recorded 687 mass shootings in the United States this year alone.
