HILO — A 19-year-old Hilo man who caused severe brain to his infant son when he hit the child’s head against a car will spend time in prison and have to pay restitution to the state.

The Hawaii Tribune reports that Kainoa Poepoe-Vigil was sentenced to 10 years Friday and ordered to pay the state $102,000 in restitution. He will be given credit for the year-and-a-half he’s already spent behind bars.

Poepoe-Vigil’s sentencing comes after he pleaded guilty in August to first-degree assault on his then 4-month-old boy.

Authorities say Poepoe-Vigil hit the infant’s head against the door frame of a car in March 2009, but did not seek medical attention for the child until the following day, when he became unresponsive.

A doctor who treated the baby at a hospital testified during the trial that the infant would have died had he not been resuscitated by paramedics.
