Overview

• Amy Louise Leonard, a 20-year-old makeup influencer from Greater Manchester, was hospitalized on September 29 at Bolton Hospital and died three days later, according to family accounts reported by multiple outlets.
• Her family confirmed the death via a GoFundMe campaign and described her as loving and full of life while asking the UK government to strengthen restrictions on nitrous oxide sales.
• Media reports citing the family attribute her death to blood clots in the heart and lungs associated with nitrous oxide inhalation, with no formal coroner findings detailed in the coverage.
