Police say Terry Span died Thursday, 12 days after the fight outside a club where the band had played. The 48-year-old Aleister Wild guitarist had been in a coma.

The coroner says the cause of death was a closed head injury.

Thirty-nine-year-old Michael Sorden was arrested on assault charges after the Oct. 8 fight. Police say prosecutors will decide whether to file other charges.

Sorden is a bass player in the band.

Another Aleister Wild member, vocalist Ernie Munoz, told The Gazette of Colorado Springs that Span was trying to calm Sorden after a dispute over loading the band members’ equipment.
