LEESBURG, Fla. -

Police have arrested a 51-year-old Leesburg man who they say downloaded the largest collection of child pornography ever found in Florida.

John Shearen, who investigators are calling the "most notorious child porn downloader they've taken into custody," was arrested around 9 a.m. Thursday and charged with 15 counts of possession of child pornography and 15 counts of distribution of child pornography.

When investigators searched Shearen's Wild Harbor Lane apartment, they discovered he had downloaded up to 1 million images and full-length videos of child porn on multiple computers and mass media storage devices, investigators said.

Shearen admitted to his crimes, police say, and other charges may be pending. He was booked into Lake County Jail on a no-bond status.

At his first court appearance, which was held Friday morning, Shearen appeared antsy and was shaking while keeping his head down.

A judge, who maintained the no-bond status, appointed a public defender to represent Shearen, who will be prosecuted by the State Attorney 5th Judicial Circuit.
