GRAND HAVEN, Mich (WZZM) -- An Ottawa County man will find out his punishment in January for shaking his infant son late this summer.
Our partner, the Grand Haven Tribune, reports 23-year-old Justin McIntyre was found guilty of second-degree child abuse Tuesday.
Investigators say McIntyre shook five-week old Bentley back in August, seriously injuring the child.
Bentley experienced a number of seizures and had a staph infection in his lungs. An MRI also indicated there is damage to the frontal lobe and back part of his brain. Bentley was released from the Helen DeVos Children's Hospital in September.
McIntyre told investigators he was frustrated with the child's crying and couldn't get him to stop.
A judge will sentence McIntyre next month.
