Lakewood Police have launched an investigation into the death of a toddler who was found unresponsive after she was pulled from a pond Tuesday afternoon.

A call first came in about the incident at 1:40 p.m. The caller told Lakewood Police the 18-month-old child had apparently fallen into a pond in the backyard of a house in the 12000 block of West Louisiana Avenue.

The girl was taken to a local hospital, where attempts to revive her were unsuccessful.

Detectives say they’re working to determine how the toddler got into the water, and how long she was there before someone helped. A family member had been taking care of the girl at the time, and said she wandered away, according to Lakewood Police.

The Jefferson County District Attorney’s Office will determine if criminal charges are appropriate.
