Earlier this month, Los Angeles County Sheriff Alex Villanueva revealed that the primary cause of the crash was speed. During a press conference, Villanueva said that Woods was driving 84 to 87 miles per hour during the crash before he hit a tree. Villanueva stressed that "no preferential treatment" was given to Woods and that they were only able to release the findings of the crash with his permission. He said that they did not conduct a field sobriety test at the time because it was inappropriate given the seriousness of Woods' injuries. Powers said that there was no evidence of impairment, alcohol, narcotics or any evidence of medication in the vehicle or on Woods, and that there was no evidence he was on his cell phone or driving during the accident.
