Authorities responded to Harrell's home after an alarm went off in June. Harrell's wife told deputies they had got into an argument that turned physical. While deputies were talking to the couple, they noticed guns and drugs in the home.
Harrell had served two years in prison for causing a fatal crash in Nashville in 2013. He testified in 2015 that he had been addicted to prescription drugs and was speeding. The band, which has had hits including "Kryptonite," suspended Harrell after a second-offense DUI in 2012.
