Crews from Onalaska helped Game Wardens search a half-mile area for several hours."We used side scan sonar and was able to get pretty good image of the victim and we called the dive team and they utilized their sonar as well," Game Warden Brandon Thacker explained.The dive team recovered his body before 5pm, hours after he was last seen around 8:30am.With no known medical problems, no one knows yet what happened to Campbell in the water and his death was too painful for his friends to talk about.
