Officials at a Stamford, Connecticut, transfer station made a macabre discovery Thursday - the day before Halloween - when they found two human skulls in a pile of recyclables brought from Fairfield, the Associated Press said. The site also revealed a human jaw bone, the news service added.

The remains belong to "an older man and woman," according to Fox News. Books and videos on witchcraft and Satan were found nearby, police told the news channel. Statements from Stamford police Lt. Diedrich Hohn seem to indicate that authorities were able to identify the skull belonging to the man.

"What we are hearing from sources and stuff is that this guy, who has passed away, was into the occult," Hohn said. "That's what we're investigating now." The lieutenant said that the jaw bone was a part of one of the skulls.

CBS Connecticut reported that Fairfield resident Robert DiVitto, 89, said his son, who went by the same name, had purchased the skulls online. He could not tell if the remains were real nor if his son had known; the younger DiVitto died this month at 56.

"I just got done talking to the police," the father told the AP. "There is no story here. They were purchased by my son as a joke."

The elder DiVitto said his son, whom he called "troubled," had been displaying the remains in the living room.

Hohn said police were looking "at all angles" to determine to origins of the skulls. "You could buy these skulls online," he admitted. "(But) we also want to make sure there is nothing sinister, that no one was murdered."

The medical examiner's office in Farmington was tasked with analyzing the find. It found no signs of trauma on either skull, Hohn said. An anthropologist will not attempt to more accurately determine the ages of the deceased. The larger skull was partially blue, which could be the result of it having been bleached, the lieutenant concluded.
