A 15-year-old girl is in custody for stealing eight guns from her grandfather, whom she lives within Cape Coral. Sierra Arredondo allegedly took two semiautomatic handguns and six revolvers from her grandpa’s bedroom in the 1300 block of SE 23rd Street. Police said Arredondo gave the guns to a friend who turned around and sold them illegally. None of the stolen guns have been found, police said.
