A man who gunned down two police officers and a woman Sunday in Las Vegas left behind social media postings that show his concerns over Benghazi, chemtrails, gun control laws, and the government’s treatment of rancher Cliven Bundy.

Neighbors identified Jerad and Amanda Miller as the suspects who shot the officers execution-style as they ate lunch at a pizza restaurant, and then shot a woman outside a Walmart in the same plaza.

The couple’s apartment was searched Monday morning, and authorities in Lafayette, Indiana, confirmed that Las Vegas police had contacted them about the case.

Witnesses said the couple announced the shootings were the start of a revolution and draped the victims’ bodies with American Revolution-era Gadsden flags — bearing the slogan “Don’t tread on me” — that have become symbols of the Tea Party movement.
