The results are in and the cause of death of former Warrant singer Jani Lane have been determined. It should shock no one that Lane, who battled substance abuse for many years and while in the public eye, died of acute alcohol poisoning. He was just 47 years old.

TMZ reports that the L.A. Coroner's Office has closed its investigation into Lane's death, concluding that he died of "acute ethanol poisoning." He was found dead in a Los Angeles area motel on Aug. 11th. A half-empty bottle of vodka and prescription meds where found in the motel room along with the singer's body.

Hopefully this news can provide some closure to Lane's survivors.
