A Rittman woman has been sentenced to 30 years to life in prison for her role in the murder of a woman nearly a decade ago.  38-year-old Erica Stefanko had previously pleaded guilty to aggravated murder in the death of Ashley Biggs in 2012. Police said that Stefanko lured Biggs to an empty parking lot of a closed business where her husband Chad Cobb was waiting.  Cobb then killed Biggs and dumped her body in a Wayne County field.  Cobb and Biggs were involved in a custody dispute at the time.  Cobb is serving life with no chance of parole for the crime.  Stefanko wasn’t arrested until two years ago for her involvement in the crime.
