MISSOULA, Mont. -

Federal prosecutors are asking a judge to sentence Jordan Graham to life in prison.

Graham pleaded guilty to second-degree murder in U.S. District Court in December.

The newlywed pushed her husband of just eight days, Cody Lee Johnson, off a cliff in Glacier National Park.

The case went to trial in December, but Graham pleaded guilty to the second-degree murder charge before the jury was given its instructions for deliberation.

In court documents filed Tuesday, Assistant U.S. Attorneys Zeno Baucus and Kris McLean recommended a life sentence or a minimum of 50 years in prison followed by supervised release.

Assistant Federal Defender Andrew Nelson and Senior Litigator Michael Donahoe wrote that Graham prays for a sentence of 10 years with five years supervised release to follow.

Both parties also filed letters in support of their sentencing recommendations. Click here for letters in support of the Assistant U.S. Attorneys. Click here for letters in support of Graham.

A sentencing hearing is scheduled for Thursday, March 27 at 9 a.m.
