An eastern Pennsylvania woman whose toddler son died in a bedroom accident after she left him unsupervised has pleaded guilty to involuntary manslaughter.

Prosecutors say Marianella Torres-Matos left her 14-month-old son and his 2-year-old sister alone in an Allentown apartment while she ran errands. They say she locked the children in a bedroom for about two hours on Nov. 19.

She later discovered a 160-pound dresser had toppled onto her son. The boy was revived but later died at a hospital.

Torres-Matos wept Thursday at the Lehigh County Court hearing, during which the 27-year-old also pleaded guilty to corruption of minors in an unrelated case. She faces up to 15 years in prison when she's sentenced Nov. 1.
