AZUSA, Calif.—Investigators say a Southern California woman killed in a rollover freeway crash had stopped in a bar for drinks before hurrying out to get ready for a court-ordered DUI class.

The California Highway Patrol says Lidia Kopach, who was convicted of drunken driving a year ago, consumed two vodka drinks and split two pitchers of beer at a Monrovia bar before the deadly crash at 2 a.m. Thursday on Interstate 210 in Azusa.

The Pasadena Star-News says Kopach told 24-year-old Daniel Martinez, who was slightly injured in the crash, that she needed to get home and for some sleep because she had to attend a court-ordered DUI education class on Thursday.

Martinez told CHP investigators he repeatedly asked Kopach to slow down before the crash.
