Singer Scott Weiland, 48, is reported to have died after going into cardiac arrest, according to TMZ. First responder audio reveals that the former Stone Temple Pilots frontman was not breathing when the incident was reported Thursday night and dispatchers were heard saying he was in cardiac arrest. A post on Weiland's official Instagram page says he died in his sleep on his tour bus while in Bloomington, Minnesota.

The police received a call Thursday night that Weiland appeared to be dead on the tour bus. TMZ reported that he was found there around 9 p.m. He was due to perform at the Medina Ballroom with his band the Wildabouts, but the show was canceled.

While cardiac arrest is being reported as the cause of death of the "Interstate Love Song" singer, no underlying cause of death has been determined yet. Authorities will continue to investigate.

Weiland long battled drug addiction and had many run-ins with the law because of it. According to Billboard, the singer was convicted of buying crack cocaine in 1995, while in 2003 and 2007 he was arrested for DUI. Weiland had also checked into a rehab facility in 2007 for heroin use, but it was reported he did not finish the program.

Sources told TMZ Weiland was no longer abusing heroin, but they believed he had slipped back into using crack. The source also said they believe he died from an overdose, but this has not been confirmed by police.

The former Velvet Revolver singer had just turned 48 on Oct. 27. He was the singer of Stone Temple Pilots from 1994 until they separated in 2002. He would go on to join Velvet Revolver alongside past members of Guns N' Roses until they disbanded. He rejoined Stone Temple Pilots in 2008, but was fired from the band in 2013. He's touring as a solo act ever since.

The "Sour Girl" singer leaves behind his wife of two years, photographer Jamie Wachtel, whom he married in 2013. Weiland also has a son and a daughter from his previous marriage to model Mary Forsberg, 15-year-old Noah and 13-year-old Lucy.
