Wyoming authorities are investigating the death of a 13-month-old baby whose body was dumped in a trash bin that was taken to a Colorado landfill.

Logan Hunter Rogers, 23, of Cheyenne, was charged Friday with manslaughter in connection with the death of little Silas Ojeda who was reported missing Wednesday.

CBS 4 Denver reported Friday that Rogers is the boyfriend of the boy’s mother. According to the station Rogers told investigators he drove Silas’ body to a community college and dumped it a garbage container.

Laramie County Sheriff’s Office spokeswoman Capt. Linda Gesell told the station a cadaver dog checked the vehicle and indicated it smelled a body.

Rogers was set to appear before a judge Friday but the hearing was abruptly canceled after Rogers asked to speak with detectives.

“His story is changing somewhat and that’s why they cancelled the court hearing,” Gesell told the station.

The boy's grandfather reported the child missing on Wednesday after the boy's mother told him she had not seen her son since Saturday, the sheriff's office has said.

CBS 4 reported that the child’s mother told detectives that Rogers had given the child to a man named Santiago who was going to take him fishing.

Cops said she did not know his last name or where he lived, the station reported.

Gesell told the station that since Rogers' arrest, the mother checked into a hospital and was not talking.

Investigators working with a sanitation company determined that trash from the container is taken to a landfill in Ault, Colorado.

They plan to start searching for the boy's body at the landfill on Monday, Gesell said.

Richard Ojeda, the boy's grandfather, declined Friday to discuss details of the case in an interview with The Associated Press because he said he did not want to jeopardize the criminal investigation.

He said his grandson would have turned 14-months-old on Friday.

"He was perfect, all grandchildren are perfect," Ojeda said. "We just want him home so we can give him a decent burial."
