An autopsy is scheduled to determine the cause of death of a 20-month-old girl who went missing from her North Port backyard Tuesday and was found in a canal a half mile away.

Ava Natalia Perry went missing around 10:15am on Tuesday when she wandered off while playing with her 3-year old sibling.

The girl’s mother did not call 911 for nearly an hour- the girl’s body was found three hours later.

Police are still investigating the incident, but say -as of now- it is being treated as an accident.
