FBI agent: Shirtless photo was meant as "joke" The FBI agent who touched off the investigation that led to David Petraeus stepping down as head of the CIA is quoted as saying a shirtless photo of him that he sent to a Tampa, Fla. socialite linked to the scandal was a "tongue-in-cheek joke" he sent to many friends and acquaintances, and wasn't meant to be sexual. Frederick Humphries tells the Seattle Times the photo was sent to Jill Kelley in September 2010. Humphries, 47, was the agent who initially saw the emails the FBI said Petraeus' biographer and mistress, Paula Broadwell, sent to Jill Kelley, a woman she apparently saw as a rival for Petraeus' affections. As a friend of Jill Kelley, Humphries took her concerns about the emails she saw as harassing to the FBI's cyber squad in Tampa in June, CBS News correspondent Bob Orr reports. The shirtless photograph of Humphries helped land him in hot water. The Times reports Humphries sent the photograph to Kelley and others, including one of the paper's reporters, in an email. The subject line read, "Which one is Fred?" The newspaper says the photo showed "Humphries -- bald, muscular and shirtless -- standing between a pair of equally buff and bullet-ridden target dummies on a shooting range." "Indeed," the Times continues, "among his friends and associates, Humphries was known to send dumb-joke emails in which the punch line was provided by opening an attached photo." Humphries, a veteran counter-terrorism agent, has now been reassigned and his status is being reviewed by the FBI. Orr quotes law enforcement sources as describing Humphries as a solid agent with a good history. Humphries played a key role in investigating a terrorist attack aimed at blowing up Los Angeles International Airport just as the year 2000 dawned and also fatally shot a knife-wielding man in 2010.
