LAS VEGAS, Nev., (AP) -- A gunman opened fire at a Las Vegas music concert killing over 50 people and injuring more than 200.
Authorities have identified 64-year-old Stephen Paddock as the shooter. His wife, Mariou Danley, was wanted for questioning and Las Vegas Police say they believe they have located her.
Two off-duty officers have been shot and killed and one on-duty officer was sent to the hospital with non-life threatening injuries.
The sheriff says they believe this was a "lone wolf".
