GRAND RAPIDS, Mich. (WOOD) — Family members of some of the Alpine Manor murder victims have filed a petition to overturn the decision to release one of the killers from prison. 

Catherine Wood, now 57, has served 29 years of her 20- to 40-year sentence in the 1987 murders. She was granted parole on Oct. 1 and is set to be released Oct. 24.  

On Wednesday, Kent County Prosecutor Chris Becker announced he wouldn’t be appealing her parole.  

Wood and co-defendant Gwendolyn Graham suffocated five elderly women in their beds at the Walker nursing home in 1987. All the victims suffered from Alzheimer’s or dementia. Wood and Graham, both nurse’s aides at the home, were reportedly trying to spell “murder” with the victim’s initials. 

Graham was sentenced to life in prison without the possibility of parole.  

Kent County Circuit Court Judge Joseph Rossi will determine what will be done with the petition.
