CHEYENNE, Wyom. -- A man has been arrested in connection with the death of a missing 13-month-old boy whose body is believed to be in a Colorado landfill.

Logan Hunter Rogers, 23, was arrested on suspicion of manslaughter and reckless child endangering.

The toddler was reported missing Wednesday night by his grandfather in Cheyenne, Wyoming. Investigators said the grandfather had not seen the child since Saturday.

"Through several interviews, we learned the child was, in fact, deceased," Captain Linda Gesell with the Laramie County Sheriff's Office told Denver7. "A party in the home took the child and dumped it in a Dumpster at our community college."

Gesell said the trash from the Dumpster was taken to the landfill in Ault, Colorado. That's in Weld County.

The Laramie County Sheriff's Office said investigators plan to search the landfill on Monday. Authorities told Denver7 they believe they have the site narrowed down to a specific "newer" area of the dump, where investigators will have to search through approximately 200,000 pounds of garbage.

The mother of the baby told deputies a man by the name of Santiago was with the baby on a fishing trip, but those allegations turned out to be false, according to Gesell. Investigators said there is, in fact, a family friend by the name of Santiago but after interviewing him, officials believe he is not involved in any way with baby's death.

Investigators have not yet released how Rogers knew the baby or the baby's mother.

Officials said the case is still under investigation and that they still have many interviews to conduct.

Investigators said they executed a search warrant at a residence in Cheyenne Thursday night and biological evidence was taken from the home.

Rogers was due in court Friday, but the hearing was postponed when Rogers decided to talk with detectives.
