A judge has convicted a man of severely injuring his son, then 3 months old. Lawrence Superior Court Judge Mary Ames delivered the verdict Monday in the bench trial of Daniel Green, 30, the Salem News reported. Ames found Green guilty of assault and battery on a child causing substantial bodily injury, but she acquitted him of permitting an assault and battery on the child. Green’s son was hospitalized in November 2012 with injuries including bleeding on his brain and retinas that caused significant vision loss and developmental delays. Prosecutors said Green, angry with the baby’s crying, either shook or threw him while the family was living in a Danvers hotel.
