CHEYENNE, Wyo. (AP) — A Cheyenne man who pleaded guilty to manslaughter in the death of a 13-month-old boy has been sentenced to 18 to 20 years in prison.

Logan Rogers, 23, was sentenced Friday for the death of 13-month-old Silas Ojeda. Silas is believed to have died around Oct. 21, and Rogers is accused of disposing of the body in a trash bin.

Searches of a landfill in Ault, Colorado, as well as various places around Cheyenne, failed to turn up any remains.

Rogers told the court in November he had used methamphetamine around the time Silas died, and that the boy fell off a counter and appeared to have suffered a concussion.

But he said Friday that his plea was coerced, and the boy is still alive.

Silas was the son of Rogers' girlfriend at the time.
