HOUSTON (AP) — The Houston home day care where four children were killed in a fire last year was run by an irresponsible woman who twice left the children alone that day to go shopping, prosecutors told jurors Thursday during her murder trial.

Investigators have said Jessica Tata was shopping at a nearby Target when a fire broke out in her home’s kitchen and that she’d left the children home alone. But prosecutors suggested Thursday that she also went shopping that morning and left behind the children, who ranged in age from 16 months to 3 years old.
