Father charged for allegedly hurting his two infant sons

OSCEOLA, Ind. -- Two twin infant boys were injured, allegedly at the hands at the hands of their father.

Multiple rib fractures, possible permanent vision loss, fluid in the brain, and an acute subdural hemorrhage. 

Those are some of the extensive and serious injuries suffered by two infant brothers.

Inside the St. Joseph County courtroom today, 21-year-old Matthew Willett faced a judge for the first time since he allegedly admitted to shaking both of sons, several times, on multiple occasions.

Willett is officially charged with two counts of domestic battery causing serious bodily injury for a person less than 14 years old. 

Each count has a maximum sentence of 16 years.

The court documents also show, for one the sons, he admitted to "putting him on the bed, from about three to four inches off the bed."

For the other one, he admitted to "hitting his back hard to try and calm him down."

After two separate hospital visits, the continual abuse was discovered.

Willett is currently being held at the St. Joseph County Jail on an $8,000 cash bond, and several limitations if he bonds out.

If he bonds out of jail, he would have to wear a GPS tracker and would not be allowed to contact his sons or their mother.

The twins' mother and her family tells me, they "had no idea a monster was living under our roof."

The mother said one of the boys has been cleared medically.
