Retired U.S. rock DJ Dave Herman, who was awaiting trial on a child sex charge, has died aged 78. The U.S. radio personality passed away on Thursday (29May14) at University Hospital in Newark, New Jersey. Herman had complained of chest pains while at the county jail and was taken to the local medical centre, but no official cause of death has been released. Last October (13), the former DJ was arrested in the U.S. Virgin Islands after he was accused of setting up a sexual encounter with a seven-year-old girl through her mother, who turned out to be an undercover police officer. Herman was accused of plotting to sexually abuse the youngster in the U.S., before reportedly purchasing plane tickets for the pair to fly to his holiday home in Saint Croix. He faced a judge in the Virgin Islands on a charge of transportation with intent to engage in criminal sexual activity, but he did not enter a plea. He was later transported to New Jersey, where local authorities picked up the case and he pleaded not guilty to the federal charge. Herman was denied bail and was awaiting trial at the time of his death. A spokeswoman for the U.S. Attorney for the District of New Jersey confirmed officials were moving to dismiss the charges, which is standard practice upon the death of a defendant. Herman enjoyed an acclaimed radio career, and fronted the popular Rock And Roll Morning Show from 1972 to 1998. His attorney, Marc Agnifilo, tells Billboard.com that he hopes the case will not mar the legacy Herman left in the radio industry, saying, "Some would say he lived his last months under a legal cloud and that's true, but we should remember him for the decades he gave the gift of music to people."
