SEATTLE (CBSNewYork/AP) — Prosecutors in Washington state filed a third aggravated murder count against a man also charged with murder in New Jersey, alleging the four killings are part of a “bloody crusade” to punish the U.S. government for its foreign policies.

King County prosecutors charged Ali Muhammad Brown, 29, with first-degree aggravated murder Wednesday in the April 27 shooting of 30-year-old Leroy Henderson in Skyway, south of Seattle.

Brown was earlier charged with aggravated murder in the June 1 shooting deaths of two young men in Seattle, Ahmed Said and Dwone Anderson-Young.

Henderson was out walking late at night when he was shot. The young Seattle men were shot a short time after they left a nightclub.

In early August in Newark, Brown pleaded not guilty to killing a college student on June 25.

Brown and two alleged accomplices are accused of killing 19-year-old Brendan Tevlin as he stopped at a traffic light in West Orange on his way home.

Prosecutors said Brown pulled the trigger while Jeremy Villagran, 19, and Eric Williams, 18, acted as his accomplices.

Investigators said Brown then drove Tevlin’s vehicle to an apartment complex on Northfield Avenue where he stole undisclosed items from the victim.

Tevlin had just completed his freshman year at the University of Richmond in Virginia and was home from college for the summer.

All three suspects face murder, robbery and weapons charges. Brown is held on $5 million bail. His public defender had no comment at that court appearance.

As WCBS 880’s Alex Silverman reported, Brown told cops his mission was vengeance and said lives are taken every day by America, so “a life for a life.”
