Woman Kills 2 in Wrong Way Crash on Calif. Freeway

Oct. 26, 2009— -- A woman driving the wrong way on a California freeway smashed her car into a pickup truck early today, killing two women and seriously injuring two children and herself.

Police said Jessica Shekell crashed her Toyota Tundra into a Chevy Silverado carrying four members of a family just before 3 a.m. in the east-bound lane of State Route 91 in Anaheim.

"We think she may have been drunk," said Officer Jennifer Hink, spokeswoman for the California Highway Patrol.

None of the family members were wearing seat belts.

The family, police said, were making the one hour drive from the theme park Knott's Berry Farm in Buena Park to their home in San Bernardino. Authorities have not yet determined why the family was on the road so early in the morning or the exact relationships between the two women and two girls.

The two women in the front seats of the Silverado – driver Sally Miguel, 44, and passenger Patricia Miguel, 30 -- were pronounced dead on the scene.

In the back seat, 11-year-old Sara Miguel sustained life-threatening injuries and Mary Miguel, 15, sustained moderate injuries, according to the CHP.

Shekell was also taken to a hospital following the accident and is in critical condition, police said. Police are awaiting the results of a toxicology screen to determine if she was under the influence of alcohol or drugs at the time of the accident.

"Blood has been taken, but has not been tested yet," Hink said. "Shekell is not going anywhere. Due to the severity of her injuries, we are waiting till we have all info we need. We will then turn over the case to the district attorney."

Hink said police have yet to interview Shekell and she was unable to take a breath test at the scene because of her injuries.
