MIAMI (AP) - A woman will serve five years of probation for the death of her 18-month-old son, who was left unattended in a truck while she worked at a pet store.

Elizabeth Cuesta pleaded guilty Tuesday to one count of aggravated manslaughter.

Police say the 41-year-old forgot her to take Diego Vega to school before arriving for work as a veterinarian assistant in May 2009. The child's father found him dead inside the hot car later that day.

Cuesta faced up to 30 years in prison if convicted. Authorities say the plea deal was ideal for Cuesta because she has no criminal history or record of abuse against her two children.

Miami-Dade prosecutor Dawn Denaro says there is "no punishment greater than the loss of one's child."
