Background: Scott was born in Tynemouth, Northumberland, North East England, the youngest of three sons of Elizabeth (nee Williams) and Colonel Francis Percy Scott (who served in the Royal Engineers). He followed in his elder brother's footsteps, studying at Grangefield School, West Hartlepool College of Art and graduating from Sunderland Art School with a fine arts degree. At the age of 16 he appeared in Boy and Bicycle, a short film marking the directorial debut of his 23-year-old brother Ridley. Scott studied art in Leeds after failing to gain admission to the Royal College of Art in London at his first attempt.
Context: On 19 August 2012, at approximately 12:30 pm. PDT, Scott killed himself by jumping off the Vincent Thomas Bridge in the San Pedro port district of Los Angeles. Investigators from the Los Angeles Police Department's Harbor Division found contact information in a note left in his car, parked on the bridge, and a note at his office for his family. One witness said he did not hesitate before jumping, but another said he looked nervous before climbing a fence, hesitating for two seconds, and jumping into the water beside a tour boat. His body was recovered from the water by the Los Angeles Port Police. On 22 August, Los Angeles County coroner's spokesman Ed Winters said the two notes Scott left behind made no mention of any health problems, but neither the police nor the family disclosed the content of those notes. On 22 October 2012, the Los Angeles County Coroner's Office announced the cause of death as "multiple blunt force injuries." Therapeutic levels of mirtazapine and eszopiclone were in his system at the time of death. Both drugs have been known to cause suicidal thoughts or ideation. A coroner's official said Scott "did not have any serious underlying medical conditions" and that there was "no anatomic evidence of neoplasia [cancer] identified." In a November 2014 interview with Variety, Ridley Scott, while describing his brother's death as "inexplicable", contradicted the coroner's official by saying that Tony had been "fighting a lengthy battle with cancer -- a diagnosis the family elected to keep private during his treatments and in the immediate wake of his death."
