1:45 p.m.

A woman has been charged with murder in the beating death of a 13-month-old girl under her care on an American Indian reservation in Montana.

The Fort Peck Tribal Court clerk's office says Janelle Red Dog pleaded not guilty during a Tuesday court appearance in Poplar.

Chief Judge Stacie Crawford denied bond and ordered Red Dog back into custody pending a May hearing.

Authorities say the 42-year-old woman beat to death Kenzley Olson on April 19, put the body into a dumpster and reported Kenzley missing.

Defense attorney Mary Zemyan says she's uncertain what killed Kenzley.

Tribal law allows for a maximum three-year prison sentence on any one charge. Separate federal charges also are expected in the case.

The baby's mother was in jail on unspecified allegations when she died.

A prosecutor says a woman on a Montana American Indian reservation will be charged with murder in the beating death of a 13-month-old girl.

Fort Peck Tribes Chief Prosecutor Scott Seifert said Tuesday that 42-year-old Janelle Red Dog could face additional charges at a later date.

Red Dog's attorney, Mary Zemyan, says her client will plead not guilty during a court appearance scheduled for Tuesday. Zemyan has noted the baby's cause of death is unclear.

Red Dog is accused of beating to death Kenzley Olson while the girl was under her care, then putting the body into a dumpster and reporting Kenzley missing.

A woman is due in a tribal court in Montana on Tuesday to face charges in the alleged beating death of a 13-month-old girl under her care on the Fort Peck Indian Reservation.

Investigators say 42-year-old Janelle Red Dog killed Kenzley Olson and put her body in a dumpster before reporting her missing April 19.

That triggered an Amber alert for Kenzley in Montana and North Dakota. It was canceled after Red Dog purportedly confessed and led authorities to the girl's body.

Red Dog's lawyer has said she admitted to authorities that she struck Kenzley on three occasions. But defense attorney Mary Zemyan said it was uncertain if that's what killed the girl.

The baby's mother was in jail on unspecified allegations when she died.

Tribal officials haven't disclosed what charges Red Dog will face. Federal officials expect to file separate charges.
