A man beat his girlfriend so viciously that he killed her unborn child and left her brain dead, police say.

Colby Wilson, 32, was arrested late Monday night in Tulsa, Oklahoma and now faces murder charges after his girlfriend, Allyssa Fielding’s baby was pronounced dead.

Officers responded to calls of a suicidal person at an apartment complex to find Wilson covered in blood while as a woman tried to give Fielding CPR on the floor.

Police noted that Wilson was ‘screaming and hollering’ and had a fresh cut on one of his knuckles.


Officers later identified the woman who was trying to revive Fielding as Wilson’s mother, who originally called 911.



She told investigators that her son called her, crying hysterically and claiming he was going to kill himself, KTUL reported.

Wilson was booked at the Tulsa County jail on multiple charges, including first-degree murder and assault with intent to kill.

Additional charges are pending, including another murder charge depending on Fielding’s survival.

According to Wilson’s mother, her son has a history of domestic violence and spent time in jail in 2016 for beating his girlfriend.
