Details are finally beginning to leak out on the circumstances of the death of Kevin DuBrow, the Quiet Riot lead singer who was found dead at his Vegas home earlier this week.

The band's former bassist, Kelly Garni, said he was alerted by DuBrow's security company on Sunday about a possible problem at the home, MTV.com is reporting. Also, DuBrow's voice-mailbox was full. "That was the first sign of trouble to me," Garni said.

Garni reportedly contact Quiet Riot drummer Frankie Banali, but Banali told him he hadn't heard from DuBrow in about 10 days. In addition, a girlfriend of DuBrow's told Garni that the singer missed a planned Thanksgiving dinner date with her. (One of two Thanksgiving dates DuBrow had that night, according to reports.)

When a paramedic was finally able to break into the house, DuBrow was found dead in his bed, MTV.com reports. There were no signs of foul play, but toxicology reports are pending.

Meanwhile, his peers in the metal world -- including Nikki Sixx, Billy Morris and Glenn Hughes are stepping forward to pay their respects. (Click here to read many of their statements on MTV.com)

"Quiet Riot put metal on the radio in the early 80's in spite of the vanilla New Wave surge of Duran Duran clones at the time," Rikki Rocket, Poison's drummer, wrote on his MySpace blog. "However he died or why, let's just remember the colossal contributions that he made."
