Lucy-Bleu Knight, the 25-year-old stepdaughter of Guns N' Roses guitarist Slash, was found dead on July 19, with the Los Angeles County medical examiner ruling her death a suicide due to hydrogen sulfide toxicity. The autopsy report revealed she had inhaled the toxic gas, which can be produced by mixing certain cleaning products, and noted a cautionary message she left for first responders warning them of the dangers. Investigators found evidence that she had attempted to seal off her living space before her death, including using blue tape on doors and light fixtures. Knight's body was discovered in a rented home after the landlord failed to receive a response from her. Slash publicly announced her passing two days later, describing her as a talented artist and requesting privacy for her family during this difficult time. The CDC warns that high concentrations of hydrogen sulfide can lead to rapid unconsciousness and death.
