The family of an Arizona State University hockey player left on life support after a near-fatal workout is demanding to know what happened to the head coach’s cell phone, which the family says may have been replaced. In an Oct. 3 letter to ASU, the family’s lawyer said the phone could contain videos, photographs, text messages and communications among coaching staff. The lawyer argued that the university was legally obligated to preserve such material. The family is seeking the phone’s whereabouts because it could contain information about the workout and the events surrounding the player’s medical emergency. The available details do not establish whether the coach replaced the device or what information, if any, it contained.
