A Seattle man who used a dating app to lure a gay male couple to their deaths says it was part of a revenge plot against the government of the United States.

Ali Muhammad Brown has confessed to killing four people, including the gay couple in Seattle, a college student in New Jersey and a 30-year-old man in Skyway, Washington.

The Los Angeles Times reported that court documents reveal that Brown told investigators that he killed the four men out of vengeance against the U.S. government for its actions in Syria, Afghanistan and Iraq.

“My mission is my mission between me and my lord. That's it,” said Brown, who is currently in custody in New Jersey. “My mission is vengeance, for the lives, millions of lives are lost every day.”

“All these lives are taken every single day by America, by this government. So a life for a life.”

Using a dating app, Brown, 29, on June 1 lured Dwone Anderson-Young and Ahmed Said to a Seattle nightclub, where he shot both of them at close range with a handgun police believe he stole from the mother of his children.

Court filings describe Brown as having “essentially executed” the couple.
