Beloved Minnesota Teacher, GSA Adviser Shot Dead

David Frigaard, a much-loved art teacher who helped strengthen relations between straight and LGBT students, was shot dead outside a St.Paul-area bar he helped run.

An 19-year-old man, whose name has not been released, is in custody in connection with the crime, which happened in the early hours of Saturday, the Minneapolis Star Tribune reports. Witnesses said that before the shooting, an underage young man grew belligerent after Frigaard refused to serve him alcohol. Some believe the man waited outside the bar until Frigaard left for the night, then shot the 46-year-old teacher and left him to die. It's not clear if the man in custody was the same one who tried to obtain a drink at the bar.

By every indication, Frigaard was an adored personality in the small community of Willernie. He taught art for years at area schools and coached track, basketball, and football. The married father was an adviser at Park High School's GSA and served as an at-risk program teacher.

"Dave was a great guy who went above and beyond to help others and he made a lot of strangers friends for life through his [bar]," read a Facebook comment reacting to his murder. "One of the most unselfish people that I've ever met, shirt-off-his-back type of guy."
