The child's screams went on for a full 30 minutes from inside the Canton, Ohio, apartment before neighbors called 911 and police arrived on-scene late last week.

They discovered that the distraught, 20-month-old boy wasn't simply left home alone. He was stuck in a toilet inside the empty apartment, WPXI in Pittsburgh is reporting.

Eventually, police did catch up with the boy's parents.

It turns out that the boy's mother, identified as 20-year-old Justice Chance, was shopping at Wal-Mart, according to the news account first reported by Fox 8 in Ohio.

Police were still at the apartment when the mother arrived two hours later, carrying Wal-Mart bags.

She reportedly told police that a sister was supposed to be babysitting. However, police said the mother couldn't remember her sister's last name, according to media accounts.

Both she and the boy's father, 20-year-old Rashaan Cuffee, who also was eventually found, were charged with child endangerment and marijuana cultivation, this for three marijuana plants allegedly found in the apartment.

The boy was apparently uninjured and turned over to child services. It remains unknown exactly how he became stuck in the toilet.
