A Kalispell, Mont., woman who pleaded guilty to pushing her new husband off a cliff in Glacier National Park last summer plans to appeal her 30-year prison sentence for his death.

Attorneys for 22-year-old Jordan Linn Graham filed the notice of appeal with the 9th U.S. Circuit Court of Appeals on Thursday. She was sentenced late last month for the death of 25-year-old Cody Johnson.

The notice says Graham plans to appeal over several issues, including prosecutors raising the issue of premeditation in a sentencing memorandum. Graham pleaded guilty to second-degree murder, which does not involve premeditation.

The notice says she also plans to appeal Molloy's decision not to allow her to withdraw her guilty plea.
