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."

RadarOnline.com has obtained the call made to 911 after the body of Warrant’s former lead singer Jani Lane was discovered at a San Fernando valley motel on August 11.

The caller calmly tells the 911 dispatcher that she works at the front desk of the motel and that the housekeepers had repeatedly knocked on the door of Lane’s  room, but that no one answered. The caller said one of the housekeepers went in and thought he was dead. The 911 dispatcher asked her to ask the housekeepers to go back into the room and make sure the person was dead.  He said, in the meantime, they would dispatch an ambulance to the motel.

Lane, 47, was carrying no official ID on him when he was found. However, alcohol and pills were found by his body, according to authorities.

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.

The current members of Warrant posted a statement on their official website Friday mourning the shocking death of the rock band’s former lead singer Jani Lane.

The band also posted an old performance video of Lane in tribute to him.
