The singer had a history of alcohol-related arrests. He was taken into custody in June 2009 for reporting crashing into a parked car. He pleaded no contest to misdemeanor DUI and was put on probation for three years.

A year later, he was arrested for a similar incident that landed him in jail for 120 days.

Lane (born John Kennedy Oswald) also served as the lyricist and main songwriter for Warrant. He joined the band in 1986, two years after its formation by guitarist Erik Turner.
