According to Washington State Patrol records, a state trooper spotted Santos driving southbound on I-5 just before midnight on July 20th, and observed Santos "slowly drift[ing]" out of her lane several times.
The trooper pulled Santos over and approached her car.
"The driver, Sharon Santos, stated she was coming from a bar. I asked Ms. Santos if she had been drinking alcohol that night, and she stated that she had," Trooper Jason Greer wrote in his report. "I could smell the odor of intoxicants coming from Ms. Santos's breath, her eyes appeared watery, and her speech was slurred."
