What the investigation first found
On Aug. 19, Seattle child sex crime detectives say they acted on a tip from the brothers' niece who arrived to clean out the garage.
The relative called 911. At the home, detectives collected a staggering amount of child porn.

They also found evidence of the sexual exploitation of young girls as well as children's worn clothing and underwear, children’s shoes, toys and movies.
Homeland Security's Internet Child Exploitation team assisted in the search, which involved digging for potential buried evidence under locked sheds and garages.
About the brothers
Neighbors in the quiet Green Lake neighborhood along Northeast 59th Street say they always wondered about the dilapidated house and the three guarded, mysterious Emery brothers who lived there since 1962.
"I've never seen a girlfriend, a wife, a woman of any type visit that house," said Don Smith, who lives next door.

Edwin purchased the house in 1962.
Seattle police say the brothers, ranging in age from 78 to 82, began molesting their own sister and eventually molested other young relatives for decades.
None of them had ever married, none had their own children or many relationships outside their own siblings.

Family tells KIRO 7 that Charles now has dementia, and they confirmed information in court documents that revealed he worked as a janitor at Seattle Children's Hospital in the 1970s and 1980s..
Police arrested 82-year-old Charles Lee Emery in a Queen Anne nursing home. Eighty-year-old Thomas Edwin Emery and 78-year-old Edwin Harold Emery were arrested at their home.
‘Manifestos’ led to more investigating
Detectives say Charles, Thomas and Edwin sexually molested young relatives for years, and collected pictures and even children's shoes.
But detectives say it was Charles' "manifestos" about Satanic rituals, kidnapping, raping and killing girls that led them to dig under sheds, searching for evidence of potential murder.
Detectives say one of Charles' writings was found buried and partially burned -- along with a child's hat. On Wednesday, detectives returned to the Green Lake house to continue searching.

"Their writings express desires to kill children," said Capt. Mike Edwards, who leads SPD's Internet Crimes Against Children (ICAC) task force. "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."
The search extended from the home in the Green Lake neighborhood to another home the brothers owned 90 miles away in Shelton.
Charging documents indicate SPD detectives questioned Edwin Emery and his relatives about child porn found on his computer in 2013, but no charges were ever filed.
Now detectives are hoping to identify the children in the photos and they hope to find victims who may have been molested decades ago and never came forward.

Family reacts to charges
Edwin's twin sister, named Edna, spoke to KIRO 7 News by telephone just a day after she got the news.
"I still haven't gotten over the shock of it," she said.

She says her daughter was acting as executor for their oldest brother's estate. That is when she made the terrible discovery.
"She was in Charles' room," Edna said of her daughter. "And I guess she was going through the boxes and stuff to see what was in them. And she found these little shoes and stuff."

The woman thought Charles might be innocent, since he has dementia.
"She said, 'I don't know if the other two were involved or not," Edna said. 'But I am going to tell the police."
Neighbors react to brothers’ charges
Neighbors have been wondering exactly what happened in this home since investigators swarmed the home over the weekend. The new details Seattle police and court documents revealed leave them stunned.
For decades, neighbors didn't think much about the three brothers who've lived there for 55 years.
“I just thought they were harmless weird old guys,” said Julie Vandenberg, who lives directly across the street.
Neighbors saw the investigators in hazardous materials suits and police bring out box after box of evidence on Friday and Saturday.

“It was shocking. I didn’t know what to think,” said Smith, who watched investigators work late into the night Friday from his home next door.
“It’s way worse than I thought. It is sickening, it's really sickening,” Vandenberg said. “Something happened to little children here - it sounds like little girls, and that's horrific.”
Neighbors say many young children live on the block.
The neighbors say they wish they would've noticed some sign earlier, about what was going on in the house but they're just glad the three brothers aren't there to victimize kids any longer.
Neighbor Don Smith said he was surprised the allegations were kept quiet for so long.
"I mean, to be next door to these guys for all these years, if. If they're going out every day and doing something like that, I was like, wow. This is too much."
