A gunman who teamed up with his wife to kill two Las Vegas police officers and an armed bystander in a weekend attack had earlier made comments to a motor vehicles office that were interpreted as a threat, but he was not arrested in that case, police said on Wednesday.
The couple, Jerad and Amanda Miller, who police said harbored anti-government and white supremacist views, gunned down the two policemen as they ate lunch on Sunday, then made their way to a nearby Walmart store where they killed an armed bystander who tried to stop them, authorities said.
Jerad Miller, 31, came to the attention of police in Nevada when he and his 22-year-old wife entered the state this year, after moving there from Indiana, Assistant Clark County Sheriff Kevin McMahill told a news conference.
Police pulled Jerad Miller over at a checkpoint as he entered Nevada, and they confiscated his driver's license because it had been suspended in Indiana, McMahill said.
Afterwards, the Southern Nevada Joint Terrorism Task Force was notified Jerad Miller had told someone at the Indiana Bureau of Motor Vehicles he would shoot anyone who tried to arrest him for driving with a suspended license, McMahill said.
