The Barbados-born beauty turned to acting after serving 15 months in a British jail for possession of LSD. A former girlfriend of rock star David Bowie, Mottley's film credits included Scrubbers (1982) and a small role in Superman III (1983), although she was best known for her starring role as "Bella" in the British television series Widows. Upset over losing her job on the series in August 1984, the 31-year-old actress' allegations of sexual and racial prejudice among the show's production crew were lost amidst a swirl of alcohol and cocaine abuse that left her 25,000 quid in debt. On February 14, 1985, St. Valentine's Day, Mottley was found slumped on her knees by the telephone in her flat in Shirland Road, Maida Vale, West London. In her depression, Mottley had downed a deadly cocktail of barbiturates and alcohol. Two notes, one addressed to her parents and tucked in her bedclothes, and the other on a writing pad begun normally in blue ink and ending illegibly in red, were found at the scene.
