AURORA, Ill. (CBS/WBBM) — Aurora Police and the state of Illinois are investigating the drowning of a 2-year-old girl at a day care facility.

The private day care facility at 2735 Squaw Valley Trail had one adult in the home, with seven children in her care — plus her own three children, according to Aurora Police Spokesman Dan Ferrelli.

“As this time, it does not appear that she was licensed to run a day care facility,” Ferrelli said. The Illinois Department of Children and Family Services was still checking on that Tuesday evening.

Ferrelli says 2-year-old Abigail Holland drowned in an above-ground pool – and even though there was a gate outside the pool, a pool toy had been leaning against the latch – making the latch inoperable.

DCFS Spokesman Kendall Marlowe says DCFS investigated a neglect allegation against the day care owner a few months ago.

“DCFS had an unfounded investigation against this babysitter concerning several children, including the deceased child, in April of this year. No credible evidence was found to substantiate the neglect allegation at that time.”

Marlowe says investigators believe it was about 20 minutes from the time the day care owner last saw Abigail – to when her body was discovered.
