(AP) — A woman whose husband was convicted of killing a Kansas woman is no longer facing charges of helping him avoid arrest.

Charges were dismissed Wednesday against Rebecca Hollister, wife of Roger Hollister, who was convicted of killing 58-year-old Patricia Kimmi of Rural Horton in 2009.

Rebecca Hollister, of Topeka, was charged in March with aiding a felon. Prosecutors had alleged she tried to help her husband avoid arrest and conviction after Kimmi’s death.

Roger Hollister died in March while serving a life sentence in the El Dorado Correctional Facility.

Nemaha County Attorney Brad Lippert said in his motion to dismiss that an essential state witness had died, making it difficult to prosecute Rebecca Hollister.
