POPLAR - A 26-hour manhunt for a 1-year-old Poplar girl ended tragically Wednesday when her body was found several blocks from her house, according to the Roosevelt County Sheriff’s Office.

A suspect is in custody and authorities declined to release further information, according to the office’s Facebook page, which has been issuing updates on the case since Tuesday.

Lee Allmer, a county spokesman, said a cause of death has not yet been determined. He said the FBI is leading the investigation.

Kenzley Ava-Lee Olson, 1, was reported to have been missing at about 12:30 p.m. from her home on the 400 block of E Street East.

At about 2 p.m. Wednesday, police sealed off a several block area east of 5th Street East and rerouted traffic while also closing the eastbound lane of U.S. Highway 2. Officers blocked off streets and alleys while officers investigated the scene and searched nearby homes and yards.

The Roosevelt County Sheriff’s Office, the Fort Peck Tribes Police Department and the FBI are investigating the case. The U.S. Border Patrol, the Montana Highway Patrol and other tribal and state agencies were also involved in the search.

Several Amber Alerts have been issued since about 2 a.m. Wednesday and were being broadcast in Montana and North Dakota. They were called off after the girl's body was found.

Why did the Amber Alert sound like that?

Some area residents were driving around Poplar looking for the girl during the night after she was reported missing.

The case took some twists and turns since the girl was reported missing. On Wednesday morning, two people of interest were found in North Dakota and after questioning were ruled out as suspects.

This is the second child kidnapping or disappearance on the reservation in the past two months.

In late February, a 4-year-old Wolf Point girl was kidnapped from a playground in west side housing and discovered nearly 48 hours later.

The suspect, John “Billy” Lieba II, 20, has appeared in Fort Peck Tribal Court and charged with felony kidnapping, aggravated sexual assault of a child and attempted murder.

He pleaded innocent to the charges and is also awaiting the possibility of being prosecuted by the U.S Attorney’s Office. He’s currently being held in jail without bond. The investigation is also continuing.

The child was discovered just outside of town 38 hours after she was allegedly taken by Lieba. She was flown to Billings for further medical treatment.
