(Buffalo, NY) On the night of April 17th, Buffalo Police say 40-year old Ali Mohamad Mohamud tied up his step-son, stuffed a sock in his mouth, covered it with duct tape, then beat the fifth grade student to death.

An autopsy showed that 10-year old Abdifatah Mohamud died after being hit 70-times with a rolling pin.

His Somali step-father is now facing second degree murder charges, and is being held in custody after appearing in court for a felony hearing.

It is now being revealed, that over the past two years, several calls were made to 911 operators from the home were the young boy lived.

On at least two occasions, it is being reported that Abdifatah call 911 to complain that his step-father was harming him.

Police responded, but no one was arrested.

"Given the tragic death of this 10-year boy and the great public concern, last week the police commissioner ordered an internal investigation into police involvement into this matter," said Buffalo Police Spokesperson Mike DeGeorge.

The Buffalo Police want to see if all procedures were properly followed, and if changes need to be made when handling domestic abuse cases in the future.
