After an initial autopsy was performed Monday, authorities are continuing their probe into filmmaker’s Tony Scott’s shocking death on Sunday.
Central to the investigation is why the Top Gun producer-director, 68, jumped off a bridge in Los Angeles Harbor. While his family is disputing a report that he had inoperable brain cancer, health issues are among possible reasons that are being explored, according to the Los Angeles County coroner’s office.
Officials said any findings have been deferred until more tests are completed, including a toxicology report for any drugs in his system.
Asked if there has been any insight into why Scott might have jumped, Los Angeles Coroner Chief Craig Harvey told PEOPLE, “Not at this time.”
