Silas was last seen in Cheyenne, Wyoming in October 2016. His grandfather reported him missing on October 26, after hearing from Silas's mother, Rhiannon Ojeda, that a man had taken her son and not returned him. When the police questioned Rhiannon, she said she'd last seen her son on October 22, before she went to work. While his mother worked, Silas was in the care of her boyfriend, Logan Hunter Rogers. He told several stories about what happened to Silas. Then he admitted he had fallen off the counter, hit his head and died the next day. He said that he put his body in a trash bin. Investigators went to the trash bin, but it had already been emptied. However, cadaver dogs detected the scent of human remains in both the trash bin and Rhiannon's car. They also found unspecified "biological evidence" in the Ojeda home suggesting Silas had died there. Silas's body has never been found.
