Nearly two months after he died in a Los Angeles motel room, county officials announced on Wednesday that former Warrant singer Jani Lane's death was a result of acute alcohol poisoning.

Lane (born John Kennedy Oswald), died at age 47 on August 11 in a room at the Comfort Inn in Woodland Hills, California. Though no cause of death was announced at the time, officials said they found a half bottle of alcohol and prescription drugs at the scene. Lane had struggled with substance abuse for a number of years.

The Los Angeles Times reported that the L.A. coroner's office determined that Lane died as a result of "acute ethanol poisoning," which translates into drinking alcohol until it poisons the system.

The singer, best known as the frontman for the 1980s glam metal band whose hits included "Cherry Pie," pleaded no contest to misdemeanor DUI in 2009 after an arrest for reportedly crashing into a parked car. A similar incident sent him to jail for 120 days in 2010. He left Warrant a number of times over the years, first taking his leave in 1993, as grunge rock took over the charts and pushed hair metal into the shadows. He came back several more times, including most recently in 2008, though he left again that same year.

Lane released a solo album, Back Down to One, in 2003. He dabbled in acting, appeared on VH1's "Celebrity Fit Club" in 2005 and toured with Great White in 2010 as a fill-in lead vocalist.
