Wichita ? The second of two sisters charged with killing a suburban Wichita man has pleaded guilty to lesser charges.

Rhonda Pischel had been scheduled for trial this week on a first-degree murder charge. She and her sister, Sharon Huddleston, were accused of killing 36-year-old Todd Stover of Park City in May 2000 by giving him a lethal dose of insulin.

KFDI-FM reports (http://bit.ly/qdoyYR) Pischel pleaded guilty Monday to involuntary manslaughter and aiding a felon.

Sharon Huddleston was convicted in February of first-degree murder and given a life sentence. Prosecutors said Huddleston was angry because Stover broke a promise to get her a job at an aircraft plant.

Stover was killed at Huddleston’s Park City home, but the sisters were living in Joplin, Mo., when they were arrested last year.
