The 9-year-old whose older brother shot and killed him on Friday in Mattapan attended JP's Hennigan School.
The brother, 14, has been charged with involuntary manslaughter and unlawful possession of a firearm, according to the Globe. Prosecutors say the older brother wasn't handling the weapon carefully when it fired.
The 9-year-old was in the fourth grade at the Heath Street elementary school. The family lives in Mattapan but very near JP, at the corner of Morton and Estella streets. Police were frequent visitors to the house, according to WCVB.
