The Los Angeles heavy metal / speed metal veterans of Hellion are mourning the death of former bassist Teddy Days, who recently passed away at the age of 48. Hellion have been paying tribute to Days since July 17, when his death was formally announced via Hellion's Facebook page.

Led by frontwoman Ann Boleyn, who arguably coined the term "speed metal," Hellion have been bringing the noise since 1982. The act has recorded four full-length albums, four EPs and three live albums, the latest release from the group being their 2003 studio album, 'Will Not Go Quietly.' Teddy Days was a member of Hellion for a short period of time in the early '90s, appearing in the 'Stormrider' video from Hellion's 1990 album, 'The Black Book.' Days passed away on July 10.

Hellion memorialized Teddy Days for the first time on July 17 through a post on the band's official Facebook page:

I just received some very distressing news a few minutes ago via a Facebook post, which makes this even worse. Former Hellion bassist, Teddy Days, passed away on July 10, 2013. Over the past year I repeatedly tried to find and contact Teddy concerning participating in the new Hellion. I left a lot of messages, but since none were returned, I don't know if he ever received them. Teddy was a mellow guy and had many good friends in Southern California. He is perhaps best remembered by friends of Hellion for his appearance on the "Stormrider" video from "The Black Book" album. If anybody has any information on what happened, please message me or call me. My thoughts and best wished go out to his family and friends.

Hellion's Ann Boleyn shared additional information about Days' death with another Facebook post earlier today (July 19). Unfortunately, it seems that Days' death was either caused by a self-inflicted gunshot wound or lethal force by police after a five-hour stand-off.

More disturbing news is coming out concerning the death of former Hellion bassist, Teddy Days.

Teddy's friends first learned of Teddy's death yesterday after an obituary was posted in an on-line newspaper. The obituary stated that Teddy died on July 10, 2013, but no cause of death was listed. Nor was there any explanation for the delay in the reporting of Teddy's death.

Late last night, someone posted that the cause of death was suicide and that he had been suffering from depression. Initially friends speculated that the timing of Teddy's death, on July 10, 2013, may have had to do Ronnie James Dio's birthday. Others speculated that, since Teddy had been monitoring postings on Facebook via a pseudonym "Slade Sin," which was not recognized by most of his friends, that he may have been upset by some posts. None of those theories made any sense to me, and I removed them from my page and Hellion's pages, especially if they blamed other musicians or incidents that happened in the 1980s and 1990s.

A few moments ago Teddy's long-time friend, Pat "PK" Kelley posted new information:

"I am so sorry to have to tell you this - On Wednesday July 10th Teddy had a incident with the police. He had been in a serious car accident a few months before and had family problems. He became erratic and extremely depressed. He ended up in a 5 hour stand off with the police brandishing a shotgun. He laid down in his hearse and called it quits. It is unknown at this time if his passing was from the police or by his choice. Please contact any of his friends that you know - he destroyed his phone and I don't really know his LA circle."
