Millions of fans have been grieving for Paul Walker's death. The 40-year-old action star passed away Nov. 30 in a tragic car crash. However, there are few reports claiming that there was no positive identification regarding Walker's death has been released by the Coroner's office until Wednesday.

Regarding Walker's autopsy, it was reported by Gaurdianlive.com, "Los Angeles County Coroner had completed an autopsy by Tuesday, but for hazy and unexplained reasons the office stated that the results were going to be put on security hold until further notice."

Various speculations have surfaced regarding the delay in the reports of Walker's death. There were few reports claiming that it was not sure who was driving the car before it was engulfed by the flames. Until now it has been reported that Rodas, Walker's business partner, was driving the car before the tragic accident.

Notwithstanding, the clashing claims, the Coroner Office believed that Rodas was driving at the time of the accident.

Another question that has surfaced was the cause of "Fast and Furious" star death. There was the involvement of another vehicle. According to Gaurdianlive.com, "The Los Angeles Sheriff's office has stated that there is presently no evidence to suggest that a second vehicle was involved in the events.
