Oklahoma man beat his girlfriend up while she was pregnant - then murdered their baby son after he was born, prosecutors say

An Oklahoma man beat up his girlfriend while she was pregnant - then murdered their baby son 10 months after he was born, prosecutors allege.  

Hunter Smiley, 25, had already been arrested by police in January 2023 for beating up the infant's mother, who DailyMail.com is not naming, while still pregnant with their unborn son.

At the time, Smiley was charged with domestic assault and battery against a pregnant woman.

He pled guilty to hitting the mother using pieces of a door he had broken while in a  fight following a night drinking.

But Smiley is since said to have murdered the child - an adorable boy named Briggs - just 10 months after the infant was born.
