The Montana Standard reports Jeremy Cramer of Lacey, Wash., is scheduled to be sentenced on April 4 in District Court in Anaconda.
Cramer pleaded guilty to deliberate homicide in December for the July 8 death of Broderick Cramer. The boy's body was found the next morning in a field about 5 miles southeast of Anaconda.
Prosecutors agreed to recommend a sentence of life in prison with no parole restrictions. Judge Loren Tucker has said he is not bound by the plea agreement.
Cramer has been jailed since Anaconda police arrested him at a convenience store, where he was trying to wash his son's blood from his clothes.
