A boy suffered an arrow wound to the head in Escondido Friday afternoon. The victim, whose age was unknown, was playing with an amateur bow and arrow set off San Pasqual Road near Bear Valley Parkway about 3 p.m. when his brother shot him, the Sheriff’s Department said. The boy suffered a wound above the eye, but the unsharpened end of the arrow did not penetrate his head, and he is expected to survive. He was flown to Children’s Hospital.
