Detectives suspect that a second body found in the carport of their duplex was the boy's missing 13-year-old brother, officials said. Relatives Wednesday identified the brother as Conrad Morales.
On Oct. 8, Cathy Sarinana had reported a 13-year-old runaway child to the Lewis County, Wash., Sheriff's Department, officials said. She was living in a Winlock, Wash., trailer park at the time.
Police have requested dental records for the older boy, whom officials did not identify, and two Corona police investigators flew to Washington on Wednesday afternoon to continue their investigation.
Raul Sarinana had been taking care of the two boys for his older sister, Rosa Morales, after she was sent to prison, according to a relative from El Monte and police officials.
"They were good little boys who just wanted attention," said the relative, who asked not to be identified because she said she feared retaliation from other family members. "We're in shock. We're trying to put it all together."
The relative, who took care of the boys for almost a year, said they had been bouncing from relative to relative for at least five years. Morales also has two older daughters, who are being cared for by other relatives, she said.
The sisters were among about a dozen weeping relatives and friends of the boys who gathered at the La Puente home of another of the boys' aunts late Wednesday, but were too emotional to speak. The family had set up a memorial to the boys consisting of candles and photographs depicting Conrad and Ricky as babies, and as young children in Halloween costumes.
The boys had grown up in La Puente and West Covina, relatives said.
Rosa's sister Bertha Cevallos, 43, said Conrad had gone to live with the Sarinanas about a year and a half ago, and Ricky joined him about six months later. Their mother, Cevallos said, was concerned about them living in Southern California through their rebellious teenage years and thought they would be less likely to get into trouble in Washington state.
Raul Sarinana and his wife sent back reports saying the boys were doing well in school and were involved in numerous activities, the family said.
Some family members worried that Conrad and Ricky seemed unhappy, and that their phone calls had a rote, practiced tone as if they were reading from a script. But they chalked this up to shyness, and did not suspect they were in danger, said Martin Cevallos, 22, of Downey, cousin to Conrad and Ricky.
He said he knew Raul Sarinana from childhood, and called him a favorite uncle. "The thought never crossed my mind that he would hurt them."
Once, a sister had requested that police make a welfare check on the boys in Washington, but never heard back, he said. The last time any of the relatives talked to Ricky was on Christmas, they said, when he told them that he missed his mother and wanted to come home.
On Wednesday, the couple's arraignment was postponed to Jan. 5 at a hearing in Riverside County Superior Court that lasted less than a minute. The pair are being held without bail at Robert Presley Detention Center in Riverside.
Charges have not been filed in connection with the second body; officials said the death may have occurred in Washington. The child protection agency in Lewis County confirmed that it had been asked to assist the investigation.
The cause of Ricky Morales' death might be determined by an autopsy to be performed today; the second boy's autopsy is scheduled Friday.
A relative tipped off police later that day that there had been another boy living with the Sarinanas, said Corona police Sgt. Jerry Rodriguez. Police contacted the Lewis County Sheriff's Department on Tuesday and returned to the residential neighborhood to search again.
Using X-ray equipment, they discovered the second boy's remains in the carport. Neighbors said they saw teams break concrete with jackhammers and roll out several green metal barrels.

Sorry GEG. A lot of times we kind of set up our own shorthand, don't ever be afraid to ask if you can't figure it out.
