Cops: Body found in water tank is likely Amari Harley, boy missing from Fla. park

JACKSONVILLE, Fla. -- Investigators in Florida have found the body of a missing 3-year-old boy in an underground water storage tank hours after the child disappeared from a family gathering.

Jacksonville Sheriff's Office Assistant Chief Scott Dingee said in a news conference that investigators believe the body found on Sunday evening is Amari Harley. An autopsy is scheduled Monday.

Authorities say Harley was reported missing from a birthday party at a city park after his family had searched for him for an hour.

The sheriff's office launched a wide search with more than 50 officers.

Dingee says "all options are on the table" for the agency's investigation, and it has not been determined if Harley accidentally fell into the water tank.

Investigators told CBS affiliate WJAX a tip led them to search the underground water tank inside the park, which they said is large enough for a small child to slip in to. Once the tank was drained, the body was discovered.

Dingee says there are covers for the tank but was unsure if they were on properly. Workers were seen placing new covers on the water tank Monday, the station reports.
