The wreck occurred in Pacific Palisades near the Riviera Country Club. According to the LAPD, the Ferrari was going "at a high rate of speed" and collided with several vehicles before coming to rest at a light pole. The driver of that vehicle, a 71-year-old man, was pronounced dead at the scene.
Haas was in one of the vehicles the Ferrari hit, and was taken to the hospital for pain and swelling in his legs. A man and woman in another vehicle were taken to the hospital in serious condition.
Luke Wilson was driving in a separate vehicle from Haas, he was involved in the wreck but not injured.
It's unclear if Haas and Wilson were at the Riviera Country Club before the wreck, where the PGA Tour is set to kick off the Genesis Open this week.
