John Nazarian, a former police officer, has been a private investigator for 20 years. He says that on average, he has about a half-dozen pro athletes a year as clients. Usually, it’s because they were involved in extramarital affairs and the mistress is seeking money for her silence. He says he recently had an athlete have GPS devices put on his wife’s car, not because he was worried about his wife’s infidelity, but because he wanted to make sure that when he was with a mistress, his wife was nowhere near. “He’d go online and see where she’s at,” Nazarian says.
