Alyn Beck, 41, one of two Las Vegas police officers slain in an ambush Sunday, had been with the department since 2001 and leaves behind a wife and three children.
He was a senior patrol officer who had taught advanced officer skills training at the Las Vegas police academy.
Tracy Smith, a friend of Beck's, wrote on his blog, "My friend Alyn was a dynamite guy. He was a riot to be around. He was kind and funny. He was capable of ridiculously juvenile behavior but also shockingly profound intellectual depth."
Smith told CNN on Monday, "Alyn was a good person — all he wanted to do was help people. He was a fine guy. We're talking about a guy who on the one hand was a deadly trained weapon, capable of a massive amount of force — strong and powerful. On the other hand, he was tender. He was gentle."
Beck, he wrote, "was an amazing father and a loyal and loving husband" who liked to swim with his kids in the backyard and was overjoyed with becoming a father again, more than a decade after raising his first two children. "He loved going dancing with his wife (a scene I could never fully comprehend!), and surprisingly, he even liked musicals."
He said Beck was a "top-notch cop" who was "the first guy through the door" during raids. "He relished telling stories about busting down the door of white supremacist gangs, about chasing down gang-bangers after a mile-long foot chase, and about consistently outsmarting bad guys. He was the guy you picture when you think of a trained weapon. He was the guy you would want showing up if you were in any kind of danger, because he was fearless and beyond capable."
In a Monday briefing, police said one of the suspects, Jerad Miller, shot Beck's partner, Igor Soldo, at point-blank range as the officers ate lunch, killing him instantly, before shooting Beck dead as he reacted.
