Leider Sentenced Today

Posted: Updated:

After entering a guilty plea in July, a 25 year old woman from the Crow Indian Reservation was sentenced in federal court this afternoon for killing her 3 year old daughter by throwing her out of a fast-moving vehicle back in December of 2012.

Authorities say Mary Agnes Leider was riding in the passenger seat with her daughter, Tenielle Big Day, in her lap, and that vehicle was going at least 45 miles an hour when Leider opened her door and threw the three year old girl onto US Highway 313 just outside of Hardin for reasons that remain unclear. Big Day, died of massive head injuries due to blunt force trauma.

Leider was scheduled to appear today before U.S. District Judge Donald Molloy in Billings after pleading guilty to second degree murder. She faces more than two decades in prison for this offense.  We will have more information as soon as it becomes available.
