Her cause of death was acute intoxication by the combined effects of fentanyl, p-fluorofentanyl, and ethanol. On July 24, 2022, the New York Police Department responded to a call about an unresponsive woman in a bedroom inside of her Eldridge Street apartment. After officers arrived, the woman was found on her bed and declared dead at the scene. Gallagher was publicly named as the deceased woman by police on Friday, according to NBC New York. She was 35.

An icon herself, she also modeled for several fellow designers and labels," it continued. "She was unique, beautiful, smart, unabashed, and always wanting. She was hardworking and talented, with so many ideas and plans for future projects. We are so proud of who she was and all she achieved in her brief but full and beautiful life. She was Katie, our daughter, sister, aunt, and friend." She leaves behind her parents, five sisters, a niece, her grandmother, and many extended "family members, friends, clients, and colleagues she met along the way."
