Jani Lane | Singer with Warrant, 47

Jani Lane, 47, former lead singer of the metal rock band Warrant, has died in Los Angeles.

Officer Sara Faden said Mr. Lane's body was found Thursday in a Woodland Hills hotel. She had no immediate information on the cause or circumstances of his death.

Assistant Chief Coroner Ed Winter said Friday that an autopsy did not reveal what killed the rocker and that the cause would be determined after results from toxicology and other tests are received.

With his long blond hair and tight leather outfits, Mr. Lane, born John Kennedy Oswald in Akron, Ohio, embodied the excess of 1980s "hair metal" rock bands. He joined Warrant in 1984 and wrote such hits as "Heaven," "Down Boys," and "Cherry Pie."

He had an on-and-off relationship with the band, leaving it in 1992 before returning and quitting again several times.

In recent years, he appeared in VH1's Celebrity Fit Club and made news for a drunken-driving arrest.
