Investigators search for bodies at home of brothers charged with child pornography

(FOX NEWS) - A child's hat, found burned inside the Seattle home of three elderly brothers arrested Monday for alleged child pornography possession, has prompted at least one investigator to search for a possible connection between the men and local missing persons cases.

Investigators have begun searching the property for possible victims after the hat - along with writings from the oldest brother, regarded as a "manifesto" by authorities - was discovered, according to KIRO. The document reportedly contained writing about "Satanic rituals, kidnapping, raping and killing girls."

A Grays Harbor Sheriff told KIRO he's investigating a possible connection between the three brothers and the 2009 disappearance of 10-year-old Lindsey Baum, who was last seen walking home from a friend's house in McCleary.

Authorities found the home of the three brothers -- Charles Emery, 82, Thomas Emery, 80 and Edwin Emery, 79 -- packed with child pornography, children's toys, girls' clothing and graphic notes about child sex abuse and homicide, according to police.

"It's very clear that these three individuals have an obsession with young female children, they've had this obsession for most if not all of their lives, and they acted on it," said Capt. Mike Edwards, who leads the Seattle Police Department's Internet Crimes Against Children (ICAC) task force. "These writings express desires to kill children."

Police say Edwin Emery admitted to molesting female family members in the past, the Seattle Times reported, though there was no immediate evidence of other physical crimes.

When Edwin took his computer to get serviced in 2013, computer store staff discovered child pornography and contacted law enforcement, according to the Times.

Monday's arrests came after a family member alerted authorities upon discovering boxes of obscene material in the garage while cleaning the home.
