The Sun Journal reports that 26-year-old Danny Adams entered the plea on Wednesday. A murder charge he initially faced will be dismissed by prosecutors.

Adams will remain jailed until his sentencing, which is set for March 24. Attorneys failed to reach an agreement on a possible sentence.

The 14-week-old boy was found unresponsive in his crib on Dec. 14, 2014, at an apartment Adams shared with the boy’s mother.The boy was pronounced dead at the scene after no neurological activity could be detected.

An investigation by the State Medical Examiner and Maine State Police determined that Zade Adams died of asphyxiation.

Adams told police he forced a pacifier into the baby’s mouth and an hour later realized he wasn’t breathing. He told police that he had been using heroin and marijuana the night before and that he was frustrated because the child wouldn’t stop crying, according to court papers.
