There is a report on CBS News
After members of the band La Excelencia in Guadalajara, Mexico refused to play more songs after closing time, irate members of the audience killed two members of the band and detonated a grenade inside the bar, Vida Divina, according to Mexican newspaper El Occidental. This is horrific. Maybe think twice about accepting a gig south of the border.
A 26-year-old woman attending the concert was also shot and injured.
According to El Occidental, four drunk men aggressively demanded the band play more after their set ended - and they did - for a while. After they stopped around 4 a.m. local time Monday morning, one of the men threw a grenade at the stage, and people ran out of the bar. As they did, two of the band members were shot.
