School officials testified that two fires Jessica Tata set caused about $2,000 worth of damage.
Jessica Tata has admitted to setting the fires because she was angry about being disciplined. She received probation and was required to undergo a counseling course called "Fire Stoppers," which is taught by the Houston Fire Department.
Houston Fire Department counselor Lisa Hayes testified that she warned Tata to think about her actions because she could kill people.
Jessica Tata's response was, according to Hayes, "I don't care."
Jessica Tata did not take the stand in her defense. Defense attorney Mike DeGeurin said he has not decided if Jessica Tata will testify in the punishment phase.
Jessica Tata faces three additional counts of murder, three counts of abandoning a child and two counts of reckless injury to a child. Trials on those charges have not yet been scheduled.
Prosecutors said Jessica Tata put the children in harm's way by leaving them alone and going shopping at a Target store. Jessica Tata's attorneys said she didn't intend to hurt the children. Defense attorneys said murder charges were excessive and that when the fire broke out, she tried to save the children.
