43-year-old Janelle Red Dog, of Poplar, Montana who was supposed to be taking care of a 13-month-old girl, Kenzley Olson who was in her care for three to four weeks, used methamphetamine while the child was unconscious and when the girl stopped breathing, she stuffed her body un a duffel bag and threw it in a trash can before going home to sleep.

This led to the unfortunate demise of the baby girl. All this while Kenzley's mother was being held in jail.

Red Dog then went to report Kenzley missing on April 19, 2016, suggesting that she may have been kidnapped.

However, a day after filing the report she confessed and took investigators to Kenzley's body.

Red Dog has reached an agreement to plead guilty to second-degree murder in the April 2016 death of Kenzley Olson.

U.S. District Judge Brian Morris has set a change-of-plea hearing for May 1 in Great Falls.

Prosecutors were prepared to show that Kenzley was ill and Red Dog who did not sick medical at the time as she was busy using meth with a friend became frustrated when she could not stop the girl from crying, she hit the girl on the head four times, causing her to have a seizure and lose consciousness, court records said.

The next morning, Red Dog decided to take the child to the hospital but said that she stopped breathing on the way.

"Red Dog, believing (Kenzley) to be dead, disposed of her body by placing her into a duffel bag and throwing the duffel bag in an alley trash can," prosecutors said.

Kezley died of multiple blunt force injuries, but an exam also noted numerous bruises from head to toe in various stages of healing, suggesting a pattern of continued physical abuse and neglect, an autopsy found.

Red Dog's mother, Rhea Starr, said her daughter was caring for kenzley when no one else would.

"That baby was passed along like yesterday's gossip," Starr told the Associated press last year.

She's not mad like she's claiming, they should send her to prison.
