So far only source is "Anon FBI" from a site which actually broke a lot of this information.

According to Victurus Libertas:

CONFIRMED FBI ANON INFORMATION One of our FBI insiders can confirmed the Intelligence community indicates John and Tony Podesta were in Praia da Luz, Portugal on May 3rd 2007– the day Madeleine McCann vanished.

The Podesta brothers were staying with a friend named “Clem.” Clement Freud, the grandson of psychopathology sex expert Dr. Sigmund Freud, who was known to be a pedophile. This is a quote from our insider: “Of greater interest is that fact that Freud owned a villa in Praia da Luz.”

Podesta erased his emails the day after the kidnapping. ( Apparently the only time hes ever decided to do this in over 10 yrs.)

.3 miles between Freuds villa and kidnapping location - I scanned area with GoogleVR: tons of backstreets with a large tourist population.(vacation villas between the hotel and Freud residence). Perfect place to commit such a crime considering that most witnesses would be transient.

Quotation is rough: infers sigmund was pederast, but Clement Freud IS a convicted pederast. Of the creepiest kind. Adoption, grooming, etc.
