Near Rosemarie Lane and Piccardo Circle in Stockton, officers tried to pull over a 2005 Buick LaCrosse driven by 20-year-old Sanchez just after 1:30 a.m. Thursday due to outdated tags and a suspended driver’s license, but she refused to stop, leading police on a short chase, according to a Stockton Police Department statement.

In September, Sanchez was released from prison on parole after being found guilty of driving under the influence and live-streaming during the crash that killed her younger sister in 2017.

“That tells us she didn’t learn her lessons while she was in prison and that she has no regard for the safety of other people,” Silva said.
