A Rittman woman faces the possibility of life in prison after being found guilty of aggravated murder.  37-year old Erica Stefanko had been accused of luring Ashley Biggs to a location where she was murdered by Stefanko’s then husband Chad Cobb eight years ago.  Biggs and Cobb were involved in a custody dispute when the crime occurred.  Cobb is already serving life without parole for the crime.  Biggs’ body was found in a field in Chippewa Township in 2012.  Stefanko was arrested last fall after police say new information came to light about her involvement in Biggs’ murder.  She will be sentenced January 11th.
