AURORA, Colo. (CBS4)– Investigators searched a landfill in Aurora for the remains of an infant that was reported missing last month.

Sharrieckia Page is accused of killing her 7-month-old son, Torrey Brown. She has been charged with child abuse resulting in death even though the baby’s body has not been recovered.

Sources told 4 On Your Side Investigator Rick Sallinger that Friday wasn’t the first time the FBI and police detectives have been searching for the baby’s remains at the Denver Arapahoe Disposal Site.

At the time of the initial disappearance investigation that began March 29, police said they believed the child was no longer alive but would not reveal why. Detectives said the child died at the hands of his mother.

At the Pinecrest Apartment complex where Page was living in Commerce City with her two other children, officers taped off dumpsters with crime scene tape while they searched the area. Officers also carried away a bassinet and other items from inside her apartment.

Investigators said they received information that Page had been seen near one of the dumpsters. If Torrey’s body was placed there, it may have gone into a garbage truck and emptied into the landfill.

Torrey’s grandmother and father told CBS4 last week that they had lost hope that he would be found alive and wonder where his body is and how he died.

“How he died and did it hurt him,” said Torrey’s grandmother Corinthian Brown. “Did he cry? Was he in pain?”

“She just said, ‘This is what you wanted, right? Are you happy?’ and then just hung up on me,” said Torrey’s father Torrey Brown, Sr. “That our hope is lost, pretty much. Once she did that, it just shows that she’s not even feeling remorseful about it.”

More details about the investigation have not been released because the case has been sealed.
