Olathe Police Sgt. Brad Caldwell said Tuesday that Kaylie Bailey, 21, and her daughter, Lana Bailey, were last seen Wednesday and were reported missing Friday.
McGill and Osladil — who had known Bailey her whole life — said Bailey had a relationship with a man who lived in the home and had planned to drop her baby off there Wednesday.
More than 40 detectives from various agencies were helping with the investigation. Olathe police are part of that group because of the open missing person case, Caldwell said.
Olathe police had provided the Franklin County Sheriff's Department with an address to check Friday, but Caldwell declined to say whether it was the same address where the bodies were found.
"We are waiting for confirmation that it may or may not be Kaylie, and once we know, it will determine what direction we go from there," Caldwell said, adding that the Olathe officers sent to the crime scene had returned to Johnson County.
So far, the missing baby doesn't meet the criteria for an Amber Alert, Caldwell said. He noted that when the missing person report was taken, there was no information that the child had been abducted.
"She left with her mother," he said.
Richards also acknowledged Tuesday that deputies had been to the scene Sunday and found nothing. He said when officers responded Monday, they got a search warrant and found the other bodies.
Osladil said she was upset with the way authorities handled the matter.
"I'm very frustrated," she said. "Without us going out there how long would it have been before they found that body?"
