LOS ANGELES (AP) — The Los Angeles County sheriff says detectives have determined what caused Tiger Woods to crash his SUV last month in Southern California but would not release details Wednesday, citing unspecified privacy concerns for the golf star.

Woods suffered serious injuries in the Feb. 23 crash when he struck a raised median around 7 a.m. in Rolling Hills Estates, just outside Los Angeles. The Genesis SUV he was driving crossed through two oncoming lanes and uprooted a tree on a downhill stretch that police said is known for wrecks. Woods is in Florida recovering from multiple surgeries.

Sheriff Alex Villanueva has been criticized for his comments about the crash, calling it “purely an accident” and saying there was no evidence of impairment. Woods told deputies he did not know how the crash occurred and didn’t remember driving. He was unconscious when a witness first approached the mangled SUV. But a sheriff’s deputy said the athlete later appeared to be in shock but was conscious and able to answer basic questions.

Investigators did not seek a search warrant for Woods’ blood samples, which could be screened for drugs and alcohol. In 2017, Woods checked himself into a clinic for help in dealing with prescription drug medication after a DUI charge in his home state of Florida.

Detectives, however, did obtain a search warrant for the data recorder of the 2021 Genesis GV80 SUV, known as a black box. Villanueva would not say Wednesday what data had been found in the black box.

“A cause has been determined, the investigation has concluded,” Villanueva said during a live social media event Wednesday.
