Park Avenue ​mass shooter Shane Tamura was “completely different” a decade ago as a star high-school athlete​ — before he ​began express​ing suicidal thoughts ​in recent years and gambling to excess while working nights as a security guard at a Las Vegas casino. ​The Midtown killer’s descent into homicidal madness stunned those who knew him growing up. “Nine years ago, he was a completely different Shane,” a 28-year-old former teammate told The Post on Tuesday — the day after Tamura shot up a Manhattan skyscraper in a failed attempt to target NFL headquarters, which he blamed for alleged brain injuries despite never playing in the league.
