LAWRENCE — Medical exams of the 9-year-old boy who police say was "savagely" beaten by his mother's boyfriend revealed he had several serious and unreported injuries in the past.
The Division of Children and Families notified police a bone scan of the boy showed likely compression fractures of four or five vertabraes in the boy's upper back and one in his lower back. It also showed a breaks in his upper arm bone, two ribs and the right pelvic bone.
Police said the report also says it is difficult to determine how old the injuries are and further testing is needed.
Thoun Rin, 31, is being held without bail on child assault charges. The boy was brought to the hospital last Friday with severe bruising to his face and lower back. He told police Rin beat him daily and he never told his mother because he was afraid he would be beaten more.
The boy said the latest beating happened last Wednesday, when Rin grabbed him by the neck and punched him in the head and struck him 10 times. The boy told police that Rin only stopped when he heard his mother coming up the stairs and walked out of the room, saying "look what happens when you jump on the bed."
Chief John Romero said the boy's mother told police her son had never broken any bones in the past. He said police asked DCF to let them know if the boy's medical exams showed something different.
Rin is charged with assault and battery on a child under 14 causing bodily injury and assault and battery on a household member.
Rin faces up to five years in prison or two and a half years in the house of correction if he is convicted on the assault and battery on a child causing bodily injury charge, and two and a half years in the house of correction and a $1,000 fine upon conviction on the charge of assault and battery on a household member.
The boy's biological father left for Cambodia on the day of the last beating, but has been contacted and is returning as soon as he can get a flight back, police said.
The DCF has taken custody of the victim and his 3-year-old brother, police said.
