3-year-old accidentally shot by sister in Rice Co.
A 3-year-old boy died after he was accidentally shot in the head by his 6-year-old sister in Nerstrand, just east of Faribault, Tuesday afternoon.
The Rice County Sheriff's Office said the children were playing in the upper level of their home when the girl found a loaded .357 revolver in an unlocked nightstand.
Officials said the children where playing with the gun when it went off, striking the 3-year-old boy in the head. The children's mother, who was downstairs at the time, found the boy and called 911.
The Sheriff's Office said the boy was airlifted from a nearby baseball field to North Memorial Medical Center in Robbinsdale, where he was pronounced dead shortly before 5:30 p.m.
