And according to a newly released FBI affidavit, investigators traced the setting of one photograph to a lodge in the Philippines, adding a troubling new dimension to the case against the 82-year-old .

The criminal complaint filed November 5 and released by the Department of Justice following Markle's November 6 arrest details evidence recovered from two storage units he allegedly rented in California for nearly two decades.

According to the affidavit, FBI agents searched the first unit on October 30, recovering approximately 27 items, including slides, film negatives, and books containing suspected child sexual abuse material.

After converting film negatives into digital photographs, an agent identified approximately 18 images believed to depict criminal conduct.
