Lilly Quinlan (b. 1974; d. Sept 2002) was the daughter of Vivian Quinlan, and an escort working in Los Angeles in the late 1990s and early 2000s. She was arrested in a prostitution sting in Las Vegas in 1999, and moved to Los Angeles shortly afterward, advertising her services on the LA-Darlings website. Her phone number was later inherited by Henry Pierce, who became obsessed with tracking down the missing Quinlan.
