TACOMA, Wash. (AP) — A former Joint Base Lewis-McChord soldier was sentenced to 20 years in prison after prosecutors said he videotaped himself raping a 2-year-old child with autism.

The News Tribune reports (http://bit.ly/2xehL3M ) 42-year-old Luis Alberto Morales was sentenced on Friday. He will have lifetime supervision after he is released and must register as a sex offender.

Morales pleaded guilty in May to producing child pornography after federal prosecutors dropped a charge of aggravated sexual abuse of a minor.

Morales' estranged wife found videos on his cell phone and showed them to Army Military Police.

Prosecutors said the mother was in the hospital when Morales raped the child.
