Five people are dead in Las Vegas after a pair of shooters killed three people and then took their own lives. The suspects reportedly shouted “this is a revolution” before shooting dead two police officers eating lunch in a restaurant. They then fatally shot a civilian inside a nearby Wal-Mart. Las Vegas Sheriff Doug Gillespie detailed how the rampage unfolded.

Doug Gillespie: “After shooting our officers, the suspects went across the parking lot to the Wal-Mart in the same plaza. At 11:27, our dispatch received a second call of shots fired at the Wal-Mart store. Two teams of patrol officers arrived on scene and did hear shots being fired. One citizen was discovered deceased inside the front door of the store. Our officers entered the front and back of the Wal-Mart store. Our officers did come in contact with suspects, at which time gunfire took place between the officers and the suspects. A short time later, more shots were heard. Preliminary, it appears the female suspect shot the male suspect, then took her own life.”

The shooters reportedly laid down “Don’t Tread on Me” flags of the American Revolutionary War on the officers’ bodies. According to ABC News, the U.S. is now averaging 15 mass shootings a year, a threefold increase from six years ago.
