Matthew Daniel  Graves, 22, from Weber County has been charged with aggravated murder – a first-degree felony,  child endangerment and drug paraphernalia possession. According court documents from Fox13 News report.

According to police reports, he told the officers he was a “monster” and had gone into a “rage” when he repeatedly punched a 1-month-old boy.

On Thursday, police were called to 4447 S. 1950 West about 7:40 a.m. on a report of an infant not breathing, according to court records.

The baby was rushed to Ogden Regional Hospital where doctors discovered significant brain trauma.

The infant was then flown to Primary Children’s Hospital where doctors said the baby had severe non-accidental trauma.

Doctors told authorities the baby had “profound brain trauma and right side fractures,” describing the fractures as “huge” and “broken” with multiple pieces spreading apart as well as “separation of the vertebrae in the neck and loss of oxygen to the brain.”

The doctors said the infant had “no brain activity.”

Graves told police that he was angry because of the baby’s excessive crying, and that he punched him repeatedly in the head.

Graves stated that he could not remember how many times he punched the baby as he blacked out from rage.

Police did not reveal his relationship with the baby. They did say that he lived in the home with the baby and a 5-year-old boy.

The boy told detectives that he saw Graves hit the baby before this incident. Police said that they found drugs in the apartment.
