MIAMI — Family members of a 13-year-old Florida girl fatally shot while riding a school bus with her younger sister say they forgive the boy who allegedly did it, but the victim’s mother insisted Wednesday that he also “has to pay for what he did.”

A 15-year-old boy was charged with manslaughter after police say he took a gun out of a backpack and showed it to other students during the ride to school Tuesday. Investigators say he fired it once in an apparent accident, striking Lourdes Guzman.

The girl, known as Jina to her family and friends and identified as Lourdes Guzman-DeJesus on her Facebook page, died later at a Miami hospital.
