The Indiana Court of Appeals has upheld a six-year sentence given to a woman convicted of helping her boyfriend escape after he killed three people.

Twenty-three-year-old Misty Davis is in prison after she was convicted in Pike Circuit Court in October of assisting a criminal and false informing.

Davis and her boyfriend, Nicholas Harbison, eluded police for more than two weeks after Harbison shot and stabbed four people in a cornfield about 35 miles north of Evansville in 2006. Only one of the victims survived.

Harbison pleaded guilty to murder and received a life sentence.

Attorney Steven Whitehead appealed Davis' conviction and sentence, arguing among other things that she was Harbison's wife and therefore immune from the charge of assisting a criminal. The appeals court rejected that claim.
