MIAMI (AP) - Trial on child pornography charges is being delayed for a former top official in South Florida's Immigration and Customs Enforcement office.
    
A federal judge on Monday reset Anthony Mangione's trial from March 5 to May 14. Mangione retired as special agent in charge of the Miami-based ICE office after he was charged last year with possessing, receiving and transporting child pornography using private Internet accounts.
    
Mangione has pleaded not guilty and is free on $75,000 bail. The charges carry a combined maximum 50-year prison sentence.
    
Mangione's lawyer asked for the delay to allow a defense expert more time to analyze computers allegedly used in the crime.
    
The 51-year-old Mangione had led the Miami-based ICE office since 2007. ICE conducts many investigations into child pornography.
