An Ocean City man has plead guilty for possession of child pornography. The Attorney General’s office announced that John B. “Jay” Mulligan III, 42, of Ocean City was among 27 defendants arrested during “Operation Watchdog” last year. In pleading guilty, Mulligan admitted that between Jan. 12, 2012 and April 13, 2012, he knowingly used Internet file sharing software to make multiple files containing child pornography readily available for any other user to download from a designated “shared folder” on his computer. Under the plea agreement, the state will recommend that Mulligan be sentenced to three years in state prison. He will be required to register as a Megan’s Law offender.
