...To learn more about what happened, the sheriff’s department then execute a search warrant to obtain the data from the vehicle’s black box, which typically shows speed, steering and braking activity before impact.

After obtaining the data, Villanueva offered some clarification on March 17 when he said there were no “obvious” signs of impairment. He then went on to talk about “lessons learned” and said, “I can tell you this: We do need more drug-recognition experts within the department.”

Drug-recognition experts (DRE) are law enforcement officers trained to recognize signs of impairment that are not obvious. After a crash, they go through a 12-step process to evaluate a driver for impairment and can request a blood examination. No DRE was used in the Woods case because Villanueva said then that it wasn’t necessary.

“We can’t just assume that somebody’s history makes them guilty,” sheriff's deputy John Schloegl told USA TODAY Sports March 2.
