A body recovered amid an intensive search is believed to be that of a missing 18-month-old girl whose mother was found dead along with two men on a Kansas farm days ago, authorities said Sunday.

Franklin County Sheriff Jeff Richards said in a statement that remains recovered in eastern Kansas on Saturday are believed to those of Lana Leigh Bailey, a child authorities previously reported as presumed dead.

'It is with great sadness that I report a body found in Osage County, Kansas, is believed to be the remains of 18-month-old Lana Bailey,' Richards said in the statement.

'I want the family of Lana, and all the victims, to know that this investigation will continue until we are confident we have collected as much evidence as we can to ensure justice is served on behalf of all four victims,' he added.

Richards said the body was discovered by an Osage County sheriff's deputy who was searching an area for items that could be connected to the deaths reported May 6 at a farm home in nearby Franklin County.

The evidence collected Saturday when the body was recovered led investigators to believe it was the infant's body, his statement said without elaboration.

'We hope that a forensic examination will make a final identification,' Richards added. 'Until the identity is confirmed investigators will continue following up on all tips, leads and information connected to this crime.'

Major search: At times up to 150 police used dive teams, police dogs, mounted patrols, planes, boats and all-terrain vehicles to scour fields, farms, ponds and creeks between Ottawa and Emporia, Kansas looking for the girl

The statement did not provide any details of where the body was discovered or how the infant had died. But his statement said a crime scene unit was called to the area 'to process this new crime scene.'

'It is not the outcome we'd hoped for but we knew we couldn't stop searching until Lana was home,' the statement said.

Richards told The AP by telephone early on Sunday that he would not have any further details beyond the statement. The Franklin County sheriff's office said its next scheduled statement on the investigation would be Sunday afternoon.

On Saturday, search crews had deployed using boats and sonar equipment in search of the child. Earlier authorities had said investigators were scouring ponds and other waterways in the area looking for the body of Lana Leigh Bailey.

Charged: Kyle Flack, 27, has been charged in the deaths of Lana and Kaylie Bailey as well as two men whose bodies were found at an eastern Kansas farm home earlier this week

Kyle Flack was charged Friday with capital murder as officials investigated the deaths of Lana Bailey's 21-year-old mother, Kaylie Bailey, and 30-year-old Andrew Stout. The 27-year-old convicted felon also was charged with multiple counts of first-degree murder in those deaths as well as that of 31-year-old Steven White, authorities have said.

The investigation had included searching the farm and other rural areas in the 50-mile stretch between Ottawa and Emporia, where Kaylie Bailey's car was found Tuesday.

Franklin County Attorney Stephen Hunting said Friday that a firearm was used against the victims at the farm, but didn't elaborate on whether that meant they were fatally shot.

Authorities have not commented on a motive.
