On a return trip to the U.S. in mid-2003, Nancy Kissel met and had an affair with Michael Del Priore, a twice-married electrical repairman who had rewired the Kissel home in Vermont. Robert Kissel became suspicious of his wife's infidelity and had hired a private detective, Frank Shea, to spy on her. Robert also secretly installed the spyware eBlaster on Nancy's computer. Nancy claimed that her husband had initiated proceedings for divorce and securing custody of their children.
