Police: No foul play in Frisco mom's death

Frisco police don’t suspect foul play in the death of a woman found last week in a McKinney parking lot.

Police are waiting for the toxicology reports to determine how Christine Woo died. They have not released details about the case, but said they are not looking for any suspects.

Woo’s three children were found alive in her SUV, which was parked near the back of a Target store about two miles away from the family’s home. A shade had been placed on the windshield.

The 5, 3 and 1-year-olds were taken to a hospital for severe dehydration. They are expected to be okay.

Investigators are also trying to figure out how long the family was in the parking lot. Woo and her three children were missing for at least three days before they were found.

It could be several weeks before the Collin County medical examiner releases Woo’s official cause of death.
