LINCOLN, Neb. -- A Bellevue woman convicted of murder will not be getting her prison sentence reduced.

The Nebraska Supreme Court on Friday upheld the 60-year-to-life sentence handed down to Alisia Cooke in Sarpy County in 2018.

Cooke was convicted of second-degree murder in connection with the 2018 slaing of 39-year-old Brent Quigley in his home.

Cooke appealed, saying she agreed to plead to a lesser charge. In return, she alleges, prosecutors said they would recommend a sentence of just 20 years.

She argued in court documents that Sarpy County engaged in prosecutorial misconduct.

The state's high court disagreed, stating that a Nebraska court is not bound to any plea agreement made by a defendant and the government.
