A former day care owner burst into tears when prosecutors played the 911 phone call made the day a fire killed four young children.
Before that, a former Target employee took the stand.
Security video shows Jessica Tata in the store on the afternoon of Feb. 24, 2011, the day of the fire.
The employee said Tata approached him about an issue with a previous purchase. After a 20-minute conversation, he told her to fill out a survey. She asked him how long that would take because she had grease cooking on the stove but had it on low and that her sister was at home asleep with the kids.
Prosecutors said she did not have a sister. No adult was found with the children.
The employee said he told her to leave the survey and get home to the kids. She left but then proceeded to stop by the Starbucks inside the store.
Prosecutors also said she went to Walmart that same morning. They point to surveillance video as proof.
Jurors also watched cellphone video of the children, recorded by Tata just hours before the fire.
Four children died and three others were hurt when grease on the stove caught fire.
Tata's attorney Mike Degeurin said his client tried to save the children and never intended to harm them.
