Task: Question Answering
Input (English): Passage: Mining engineer Mike Lambert takes a temporary job driving a truck.  When the brakes fail while coming down a steep highway, he steers his way through a small town and is lucky to just dent the pickup of Jeff Cunningham.  Jeff demands Mike's employer pay for the damage, but the man refuses. Mike pays him himself. Later, the police find Mike in a bar and arrest him for reckless driving and having an expired license.  A total stranger, barmaid Paula Craig, pays his $50 fine. When Mike gets drunk, Paula quits her job and finds him a hotel room. Then she meets Steve Price and tells him, "I found him", a stranger with the same height and build as Steve.
The next day, Mike goes looking for a job. The clerk at the assay office puts him in touch with Jeff, a prospector who has found a rich vein in an old, abandoned silver mine. He offers to cut Mike in for 10%, a generous offer he quickly accepts. However, Mike makes the mistake of telling Paula all about it. When Jeff goes to get financing from Steve, the vice-president of the Empire Bank, Paula gets him to turn Jeff down. 
An opportunist, Steve obtained his position through his wife Beth's father. He has embezzled $250,000 from the bank and hidden it in Paula's safety deposit box. The plan involves a fatal, fiery car crash, with Mike's body to be mistaken for Steve's.
Mike wins some money in a craps game and pays Paula back everything she spent on him. He saw her get in the car with Steve, and is very suspicious of a barmaid with lots of money. Paula tells him she persuaded Steve to reconsider Jeff's financing. 
Question: What is the full name of the person that has a wife named Beth?
Output (English): Jeff Cunningham.
