A 27-year-old Greek son of a priest blamed a porn overload for him raping and killing a California scientist who vanished from a conference in Crete, local authorities said.

Giannis Paraskakis, who confessed to the murder of 59-year-old Suzanne Eaton, told authorities that watching too much hardcore porn led him to murder, the Times reported.

The married father of two said the porn bender was an unsuccessful attempt to liven up his “miserable life” — and the grisly killing became an “act of despair,” according to authorities.

During an interrogation, Paraskakis said he encountered Eaton on June 2 and, “motivated by sexual satisfaction,” rammed into her twice with his car, ABC News reported.

The murder suspect claimed he stuffed an unconscious Eaton in the trunk of his vehicle. He then drove to a remote World War II bunker near Xamoudochori, where he raped her and left her for dead. authorities said.

Eaton — a molecular biologist at the Max Planck Institute in Dresden, Germany — was reported missing by colleagues after she missed several sessions at an Orthodox Academy of Crete conference.

Her body was recovered from inside the bunker July 8 with “many broken ribs and face bones as well as multiple injuries to both hands,” authorities said. Her cause of death was ruled asphyxiation.

Murder charges are expected to be filed against Paraskakis in the case, the Times reported.
