A Florida woman holding her 11-month-old son in a baby carrier was fatally shot by her 14-year-old brother while trying to defuse an argument over Christmas gifts he was having with a 15-year-old brother who also was armed, authorities said.

The 15-year-old brother then shot his 14-year-old brother, though not fatally, for killing their sister on Sunday in Largo, Florida, which is located in the Tampa metro area, the Pinellas county sheriff's office said in a news release.
