Christine Woo, the Frisco mother who was found dead inside her SUV in the parking lot of a McKinney Target late last month, committed suicide by overdose, according to the Collin County medical examiner.
Woo had been missing for three days before she was found inside her vehicle on April 1. Her three children; 5-year-old Lauren, 3-year-old Nathan and 16-month-old Leah, were found alive in the vehicle with her.
"The investigation...demonstrates that there was no deliberate plan by Woo to harm her three children," Frisco Police said in a statement Thursday.
Christine's husband, Brandon Woo, said his wife and kids had been missing since he came home from work to an empty house on March 28. He reported them missing the following day.
A Frisco Police deputy found Woo and her children around 6:30 p.m. March 31 in the parking lot of a Target on the 8900 block of State Highway 121 in McKinney.
Because Texas CPS is involved in the case, no further information would be released, police said.
