Former radio host Dave Herman died yesterday while awaiting federal criminal charges in connection to a child sex sting operation that landed him in jail last year. He was 78 years old.

Herman, who was the host of popular radio show The Dave Herman Rock and Roll Morning Show for nearly three decades before retiring in 1998, was busted in October after federal agents caught him allegedly trying to transport a young girl from New Jersey to the Virgin Islands to have sex with her. Investigators claimed he was involved in an email and phone correspondence with a woman named "Kris,"—really an undercover agent—who he he believed was the mother of a 7-year-old girl named "Lexi." Herman allegedly had multiple phone and online conversations with "Kris," about sending the young girl to St. Croix so they could engage in sexual activity. He was arrested at the St. Croix airport on October 25th and charged with interstate transport of a minor for sex.

Herman pleaded not guilty to the charges, but he was denied bail; attorney Marc Agnifilo argued he had been tricked by the undercover agent. He was in jail in New Jersey, but was rushed to University Hospital in Newark on Wednesday after complaining about chest pains. He died yesterday of undisclosed causes, and the US attorney's office for the District of New Jersey says they are moving to dismiss the charges. He was set to go to trial in July.

During his time at The Dave Herman Rock and Roll Morning Show, which ran on New York radio station WNEW-FM from 1972 to 1998, and throughout his career, Herman interviewed a number of music legends, including Bruce Springsteen, Mick Jagger and Bob Dylan.
