The Latest on the death of a 1-year-old girl on Montana's Fort Peck Indian Reservation (all times local):

10:30 a.m.

A federal investigator says a woman beat to death a 1-year-old girl on a Montana Indian reservation and threw the baby's body into a dumpster.

Forty-two-year-old Janelle Red Dog appeared in Fort Peck Tribal Court on Friday in the death of Kenzley Olson. Court officials say she didn't enter a plea and was returned to custody.

KTMF-TV reports (http://bit.ly/1VH42wl ) Bureau of Indian Affairs investigator Ken Trottier says Red Dog confessed to punching Kenzley several times on Tuesday, killing her. She then put the girl's body into a duffel bag and threw it in a dumpster.

Trottier says Red Dog reported Kenzley missing, prompting authorities in Montana and North Dakota to issue an alert for a kidnapped child. The relation between Red Dog and the girl is uncertain.

Red Dog's attorney, Mary Zemyan, didn't immediately return a telephone message from The Associated Press seeking comment.

A suspect is scheduled to appear in tribal court Friday in the death of a 1-year-old girl on Montana's Fort Peck Indian Reservation.

But much remains unknown in the case. Citing the ongoing investigation, authorities have declined to identify the 42-year-old female suspect or say what charges she faces. They also wouldn't say how Kenzley Olson died or whether the woman and baby were related.

Authorities initially said Kenzley was abducted from her home this week in the small town of Poplar. The girl was found dead Wednesday.

FBI spokeswoman Sandra Yi Barker couldn't confirm whether authorities still believe she was kidnapped.

It was the second major event in recent weeks to rattle residents of the sparsely populated reservation near the U.S.-Canada border. Authorities say in February, a 4-year-old was abducted from a Wolf Point park by a man who sexually assaulted and tried to kill her.
