JACKSONVILLE, Fla. -

A 21-year-old Palm Coast man was sentenced Monday to 10 years in federal prison for receiving child pornography over the Internet.

As part of his sentence, Kamil Mezalka is also required to serve a 10-year term of supervised release following his release from prison, and ordered to forfeit his computers and other digital media.

According to court documents, in March, a FBI agent from Philadelphia began an Internet undercover investigation to identify people using a particular file sharing program to obtain and share child pornography. Using a computer, the agent logged into the file sharing program and saw that someone using a particular screen name was logged into the network.

The agent browsed the user's shared directory and saw that more than 4,000 files were being shared therein, many of which contained titles and descriptors indicative of child pornography and the sexual abuse of children.

The investigation revealed that during the time frame of the two download sessions, the particular IP address was issued to an account registered to someone at a home in Palm Coast where Mezalka lived.

On May 8, FBI agents executed a federal search warrant at Mezalka's home. As agents gained entry to the home, Mezalka came out of a second-floor bedroom, saw the agents, and quickly turned and went back inside the same bedroom and closed the door. Despite repeated commands to come out of the bedroom, Mezalka remained in the bedroom and proceeded to use a Samurai sword to try to destroy his computers and CDs.

Agents made entry into Mezalka's bedroom, where he was eventually arrested. During an interview, Mezalka admitted to, among other things, having a file sharing program on his computer, which he used to download pornography that included child pornography. He further stated that most of it would be on the laptop computer and that some of the images might be on the desktop computer.

During the search, the agents seized, among other things, a desktop computer and a laptop computer. Both of these computers were damaged by Mezalka's use of the Samurai sword. Subsequent forensic analysis revealed that one hard drive contained more than 12,000 images and more than 3,000 videos, of which at least 500 images and 100 videos depicted child pornography.
