Brandon Woo, Christine's husband, didn't report her missing until 24 hours after she disappeared because he falsely believed he had to wait to file the report.
The Collin County medical examiner said Woo killed herself with an overdose.
The mother of three was reported missing by her worried husband after she and the kids didn't return home on Monday night. He had last seen them Monday morning when they left the house to run errands.
"Got to the house, no kids, no wife, so I'm thinking, 'OK they may be out at the playground, shopping, somewhere,' so I give her a call, call her cellphone. Cell phone rings in the other room," Brandon Woo told the newspaper. "She doesn't have her cellphone, can't track her from her cellphone."
Christine Woo hadn't packed anything or done anything else to indicate that she intended to flee, according to police.
Brandon Woo didn't file a missing person's report until Tuesday afternoon because he thought, incorrectly, that he had to wait 24 hours to do it based on something he'd heard on TV or from the movies, WFAA reported.
Credit card records and surveillance footage show that Christine Woo had gone to a Walgreen's at 9:45 a.m. on Monday to pick up an eczema prescription for her youngest child, Leah.
Surveillance video showed Woo and her children shopping at a local drug store about 15 miles from where she was found dead.
"The investigation demonstrates that there was no deliberate plan by Woo to harm her three children," Frisco police said in a statement.
Woo, a stay-at-home mom and volunteer at a local church, is a Texas A&M University graduate, where she studied business, the newspaper reported.
The children, a 5-year-old girl, 3-year-old boy and 1-year-old girl, were taken to a hospital for evaluation, police said. Local media reported that they were severely dehydrated.
