A man is facing a first-degree murder charge in connection with the death of his 2-month-old son Monday.

Fayde Riggin, 22, was charged in the death of Mavrik Riggin, said Sgt. Chris Widmer, a Tucson Police Department spokesman.

Riggin, who was booked into the Pima County jail, is also facing a child abuse charge, Widmer said.

On Aug. 12, police were dispatched to the 1200 block of South Turquoise Vista for a report of an unresponsive infant boy, said Widmer.

The neighborhood is south of East 22nd Street and east of South Kolb Road.

The child was taken to the hospital with life-threatening injuries, Widmer said. He said that hospital staff contacted police and told them the injuries to the child were non-accidental.

Detectives of the dependent child unit found out that the boy's father had recently moved back into the home with the the mother and the baby.

Investigators discovered that the father grew frustrated with the baby and shook him multiple times over a month-long period, Widmer said.

Mavrik sustained serious internal injuries from being shaken, said Widmer.

Widmer said it only takes a few seconds of shaking to cause permanent damage to a baby.

If a baby does not stop crying, the child can be put in a crib, and the caretaker can take a short break to calm down, Widmer said.
