Slash's stepdaughter Lucy-Bleu Knight's chilling suicide note with warning for first responders is revealed as full autopsy report is released after tragic death at 25

The autopsy report on the death of Guns N' Roses guitarist Slash's stepdaughter Lucy-Bleu Knight has finally been released in full.

Knight was found unresponsive on July 19 and was pronounced dead the same day at 3 p.m. local time.

The report, which was obtained by DailyMail.com, was released after the Los Angeles County's medical examiner announced in a statement late last month that Knight had died of hydrogen sulfide toxicity, while the manner of death was ruled a 'suicide.'

The new full autopsy report shares more details about Knight's condition, and reveals the disturbing note she left with a warning for first responders.

Knight was determined to have died as a result of inhaling the toxic gas, which is naturally occurring and can also be found in sewage treatment plants and oil refineries.

However, it can also be created by mixing certain cleaning products.

First responders entering the home could have been at risk of poisoning or even death from lingering gas, but Knight had placed a note on a trash can that would be immediately visible in the kitchen when someone opened the front door.

'CAUTION CALL HAZMAT IM SO SORRY H2S GAS TOXIC DONT ENTER,' Lucy-Bleu wrote on the note warning anyone who entered to check on her. 

Investigators noticed that blue tape had been used to apparently seal the cracks in the door, and the tape was also placed over light fixtures, on electrical outlets and covering ceiling air vents.

According to the report, Knight's body was discovered in the bathroom, where she was lying on her back on the floor.

In addition to the tape that had lined the windows, responders also observed black plastic bags lining the bottom of the bathroom's walk-in shower.

According to the report, Knight had checked into a short-term rental house, and her body was only found after the landlord, who had rented other properties to her in the past, didn't receive a response after messaging her. 

When officers arrived on the scene, they observed a suction sensation when the front door was opened, and they also detected a chemical odor while spying the note, so they paused and called a Hazmat team to ensure the area was safe to enter. 

Knight's body was believed to have been leaning against the bathroom before the door was forced open.

According to the report, lividity, the postmortem lack of color in the skin, had already set in, as had rigor mortis.

Investigators also observed a dark discoloration on Knight's lips.

Responders reportedly found multiple prescription medications in the rental home, including the antidepressant escitalopram and the atypical antipsychotic paliperidone, which is usually for treating schizophrenia and schizoaffective disorder.

The medical examiner's earlier report on Knight's death noted that she had 'a history of undiagnosed mental illness,' and also said her family had indicated that 'she was paranoid and would have hallucinations.'
