HOUSTON --A Montrose man faces six counts of child pornography, but authorities say with what they found, they could charge him with even more. Peter Kingman Lindsley is facing six felony charges of possession of child pornography after federal agents arrested him in his Montrose apartment. When the Department of Homeland Security picked up Lindsley at an apartment complex in the Montrose district of Houston on Monday, they found 15,000 images of child pornography on a computer in his bedroom. The pictures included girls and boys who had not reached puberty. "The pictures and images, they depict young children and it's definitely child pornography," said prosecutor John Wakefield. Lindsley appeared in probable cause court on Tuesday on the six charges of possession of child pornography filed by the Harris County District Attorney's Office. The assistant district attorney prosecuting Lindsley says he was caught because he was sharing those pictures with other people. "Officers detected an IP address that was sharing child pornography through the Internet and this IP address was then traced to his house, which is in the Montrose area," said Wakefield. The prosecutor could have filed a felony charge of possession of child porn for each image found on Lindsley's computer. "It could be 15,000 separate charges, but we would never do anything like that because the docket would be out of control," said Wakefield. If Lindsley is convicted of all six counts, he could be in prison for up to 60 years. "It's two to 10 years each case," said Wakefield. We called and a left a message for Lindsley's defense attorney on Wednesday afternoon, but have not heard back. Lindsley is due back in court on March 3. Lindsley is being held on $30,000 bond for each count.
