A couple who admitted killing their 2-year-old son and allegedly tried to cremate his body on a barbecue grill have been sentenced to prison.

Wayne County Circuit Judge Michael Callahan on Thursday sentenced 29-year-old Joseph Miller to 22 to 50 years in prison for second-degree murder and 25-year-old Nickella Reid to 10 to 15 years for involuntary manslaughter.

The Detroit couple pleaded guilty last month to those and other lesser charges.

Police found Deuntay Miller's remains while investigating the 2007 scalding of the couple's 1-year-old son. Prosecutors say the couple continued collected Deuntay's welfare benefits after his death.
