Convicted killer's ex-wife charged in pizza delivery driver's murder

NEW FRANKLIN, Ohio (WJW) -- The ex-wife of a man serving a life sentence for murder is now behind bars in the same case.

Ashley Biggs, 25, was working for Domino's Pizza in Green on June 20, 2012 when she went missing. Biggs was strangled and left in her car in a Chippewa Township corn field. Her body was found the next day and police charged her ex-boyfriend and father of her child, Chad Cobb.

Cobb pleaded guilty to aggravated murder and more, and was sentenced to life in prison without the possibility of parole.

On Monday, New Franklin police arrested Erica Stefanko, 36, formerly known as Erica Lyon, on charges of aggravated murder, kidnapping, aggravated robbery, felonious assault, retaliation, tampering with evidence and abuse of a corpse.

New Franklin police said Stefanko ordered the pizza the night of Biggs' disappearance, in order to lure her to a closed business.

Stefanko and Cobb were married at the same time Cobb and Biggs were involved in a custody battle over their young daughter.
