LAS VEGAS (AP) -- Police say a shopper armed with a concealed weapon inside a Las Vegas Wal-Mart confronted an armed man who entered the store with his wife moments after the couple killed two officers in a nearby restaurant.
Assistant Sheriff Kevin McMahill said Monday that 31-year-old Joseph Wilcox of Las Vegas was in the checkout line when he saw Jerad Miller fire a shot and went to confront him.
Miller's wife, Amanda, pulled out a gun and shot Wilcox in the rib area. He collapsed and died.
McMahill says Wilcox wasn't able to fire any shots.
Police say the Millers exchanged gunfire with officers inside the Wal-Mart before Amanda Miller shot her husband and then herself.
Investigators are looking into whether the husband and wife who shot and killed two Las Vegas police officers over the weekend had been at Cliven Bundy's Nevada ranch during a standoff earlier this year, police said Monday
Assistant Sheriff Kevin McMahill said the two suspects, Jerad Miller and his wife, Amanda, had ideology that was along the lines of "militia and white supremacists" and that law enforcement was the "oppressor."
McMahill said the shootings were an isolated act and officers were still looking for a motive.
The two officers were having lunch at a strip mall pizza buffet when the Millers fatally shot them at point-blank range in an ambush. The suspects then fled to a nearby Wal-Mart, where they killed a third person and then themselves in an apparent suicide pact, authorities said.
The attack at a CiCi's Pizza restaurant killed Officers Alyn Beck, 41, and Igor Soldo, 31, who are both husbands and fathers. Jerad Miller yelled, "This is a revolution!" McMahill said.
McMahill said at a news conference Monday that both suspects fired multiple shots into Beck. They then placed a note, a yellow "Don't tread on me" flag and a swastika on the officers' bodies.
The deadly rampage in the aging shopping center about 5 miles northeast of the Las Vegas Strip took place in a matter of minutes.
Police were called at 11:22 a.m. to the pizzeria. Shots were reported five minutes later at a nearby Wal-Mart, where the shooters gunned down 31-year-old Joseph Wilcox of Las Vegas just inside the front door and exchanged gunfire with police before killing themselves, authorities and the Clark County coroner's office said.
