A 24-year-old man is suspected of assaulting a set of Kennewick triplets.
Police arrested Demetrias Williams on suspicion of three counts of second-degree assault of a child. He was booked into the Benton County jail.
A 5-month-old went to Kadlec Regional Medical Center earlier this month for an unspecified illness, police said. Doctors discovered the infant had cracked ribs during a x-ray.
Police say the infant also had other bone fractures that were consistent with abuse.

Doctors then had x-rays done on the infant’s siblings, which revealed similar rib fractures, police said.
Police interviewed Williams and he admitted to he was “responsible” for the infants’ injuries, police said.
