Two Georgetown men and a man from New Castle were charged in connection with child pornography following an investigation by the Child Predator Task Force.

Investigators received a tip from the National Center for Missing and Exploited Children about child pornography distributed in Delaware, which led them to a home in New Castle, said Attorney General Beau Biden in a press release.

Investigators conducted a search at the home and discovered photos of nude girls and a video of one changing her clothes, Biden said. Police arrested Rogelio A. Cordero, 55, on Dec. 21 and charged him with 25 counts of dealing in child pornography. He was committed to Howard R. Young Correctional Institution in default of $375,000 secured bail.

Cordero's arrest led police to a Georgetown man. Police searched the home of David M. Pennington, 70, of the 19000 block of Substation Way and found DVDs and other documents, Biden said. Investigators also searched a storage facility in Georgetown on Jan. 8. Pennington - who is a registered sex offender on probation for a 1994 conviction of unlawful sexual intercourse - was charged with violating his probation. He was committed to Sussex Correctional Institution in default of $50,000 cash bail.

Another Georgetown man, William D. Zimmerman, 63, was charged with 25 counts of dealing in child pornography after investigators discovered he exchanged illicit images with Pennington, Biden said.

Police searched Zimmerman's home in the 300 block of N. King Street on Jan. 8 and found images of child pornography including a prepubescent boy in a sex act with an adult man, Biden said.

Zimmerman, a registered sex offender, was committed to SCI in default of $500,000 secured bail.
