Last month, the Las Vegas Medical Examiner's office confirmed to E! News that 30-year-old Boyce, who played Tyler Crowley in Twilight, and his 27-year-old girlfriend Natalie Adepoju had been pronounced dead on May 13. At the time, Boyce and Adepoju's cause of deaths were still pending. Now, the Clark County Coroner's Office told that Boyce and Adepoju both died of drug intoxication and their deaths are ruled accidental. A source previously told that they both were found deceased in Las Vegas. The source added that, prior to his death, he was really focused and handling a lot of business. And though he had moved to Las Vegas to help his mother, he would commute to LA for acting jobs and to see his daughter. Another source also shared some insight into Boyce's life prior to his passing. “Greg was definitely a person who loved life; he was the life of the party. I will definitely miss him,” the insider told.
