The Las Vegas Aviators minor league baseball team also displayed Abdelnabi’s name on the scoreboard at Las Vegas Ballpark and held a moment of silence for him Tuesday night. The suspect “immediately opened fire upon officers” after officers contacted the suspect, Seely said, and at least one officer returned fire toward the suspect. He added that the officer killed was one of the initial responders. Last year, 46-year-old North Las Vegas police officer Jason Roscow was killed in a shootout with a suspect.
