A Vermont woman convicted along with her husband of killing a prep school teacher after they decided "to get a girl" has been sentenced to life in prison without the possibility of parole.

Patricia Prue was sentenced Friday, a day after she gave up a possible insanity defense and changed her plea to guilty in the 2012 death of St. Johnsbury Academy teacher Melissa Jenkins.

Prue's husband, Allen Prue, is serving a life sentence for murder.

Patricia Prue apologized to the Jenkins' family and said she wished she had gotten mental health help.

The Prues lured the 32-year-old from her home with a ruse about a broken-down car, strangled her and dumped her body in a river.

Jenkins' vehicle was found idling on a road with her 2-year-old son inside.
