HOUSTON (AP) — A prosecutor says a Houston woman charged with murder after a fire at her home day care killed four children has betrayed the families who trusted her with their kids’ lives.

Jessica Tata’s trial in the death of one of the four children began Wednesday.

Prosecutor Steve Baldassano told jurors the case was about “trust and betrayal.” He said prosecutors would prove Tata was shopping at Target when the fire started.

Tata’s attorney, Mike DeGeurin, says his client had no intention of harming anyone. He says Tata had always dreamed of caring for children.

The 2011 fire at Tata’s home day care also injured three other children. Tata is initially being tried in the death of 16-month-old Elisa Castillo.

She faces up to life in prison if convicted.
