BOYNTON BEACH, Fla. (AP) - Investigators say the 2-year-old boy found wandering a street in Boynton Beach had been left in the care of two teenage aunts when he disappeared.

The Boynton Beach Police Department says a motorist found the toddler, Strogoff Prevot Jr., Tuesday evening. He was wearing only a pair of blue jeans and did not know his name.

Spokeswoman Stephanie Slater says the boy's parents were located at about 9:15 p.m.

Detectives determined that the child's mother, Floriante Petit-Bien, works and attends school at night. His grandmother left the boy in the care of his aunts, ages 13 and 16.

The girls fell asleep while watching the child and did not realize he had wandered away.

The toddler has been temporarily released to his father's custody.
