A 15-year-old boy is in critical condition after his cousin apparently shot him in the head by accident on Tuesday. Police responded shortly before noon to the reported shooting at a trailer park on South Zarzamora Street near West Ansley Boulevard. The victim's 15-year-old cousin reportedly had been showing him a handgun when it went off. The wounded boy is in University Hospital. The two teens were at home with four other kids, ages 16, 11, seven, and five. Officers are trying to find out how they got hold of the gun.
