Opal "Mack Truck" Long
Opal Long didn't earn the nickname "Mack Truck" for nothing, but I'll bet no one called her that to her face. She was a big, strong gal.
Not only was she a prolific shoplifter, she hung out with the Dillinger gang - part of the group because of her husband, Russell Clark.
She kept house and cooked for the gang - just like any quiet homemaker would do. In reality, she was far from quiet and obedient. When the police showed up to arrest she attacked them. Later, she was arrested herself.
Opal Long may have been a lot of things, but she wasn't a rat. Not a word did she tell the cops about the activities of the notorious Dillinger Gang!
