Investigators concluded the altercation arose when Mills was upset at a Walmart employee for leaving a cart full of merchandise in the aisle. Things escalated when Stephenson approached Mills and said:
"You must really hate your life."
Stephenson allegedly left the scene, only to return minutes later when she and Mills entered an exchange of nasty comments to one another — this escalated into a fist fight in the aisle!
Though Stephenson is in trouble because she ordered her son to:
"Punch (Mills) in her face … punch her in her (expletive) face!"
This command can clearly be heard in the recording, which led the little boy to kick Mills in the face and head!
Stephenson was charged with neglect of a dependent and contributing to the delinquency of a minor, and could lead to jail time if she's convicted.
