A boy of 11 accused of killing his father’s pregnant fiancee with a shotgun will be tried as an adult, a judge ruled today.

AN 11-year-old boy accused of killing his father’s pregnant fiance had been making threats about harming the woman for a while, the woman’s mother said yesterday.

A US jail warden said yesterday he would ask a judge to move an 11-year-old boy accused of killing his father’s pregnant girlfriend to a juvenile detention centre.

An 11-year-old boy shot his father’s pregnant girlfriend in the back of the head while she was in bed, then got on the school bus, authorities said.
