It has been almost two weeks since Warrant singer Jani Lane's body was mysteriously found in a Los Angeles hotel room and his family members are upset about how his death is being handled by those closest to him.

In an exclusive interview with RadarOnline.com, Lane's sister Vicky Oswald-Ley revealed her heartbreak over having to find out details of her brother's death from the Internet instead of from his third wife (Kimberly Nash) and his longtime manager.

"I am just so angry right now," Oswald-Ley told RadarOnline.com. "It's just very sad. I don't even have Kimberly's number but I know she has mine and she hasn't called."

The mysterious death of Warrant singer Jani Lane has shocked fans across the world and left his mourning family with endless unanswered questions.

"Alcoholism is not something he chose," Lane's older sister, Vicky Oswald-Ley told RadarOnline.com in an exclusive interview. "It’s something he fought everyday and it just won."

Lane was found dead at 47 in a Woodland Hills, Calif. Comfort Inn on Thursday at around 5.30 p.m., although the cause of death has not yet been determined, Vicky is convinced that drink, not drugs, was the reason.
