MINNEAPOLIS (WCCO) — The Hennepin County Medical Examiner has determined that the 2-year-old Minneapolis boy who was shot by his brother died of a gunshot wound to the chest.

Neejnco Xiong and his brother were playing inside the family’s townhome on 7th Street near Cedar Avenue last week. Both of the boy’s parents were home at the time.

Xiong’s 4-year-old brother was playing with a loaded handgun in the upstairs bedroom when it accidentally went off.

Paramedics tried to revive 2-year-old Xiong, but he died before getting to the hospital.

Police said the boys were home with their parents at the time along with their 1-year-old brother. Their 5-year-old brother was at school. All three siblings were put into protective custody after the shooting.

No charges have yet been filed in the incident. State law does say it’s a crime to have a loaded gun in a home where children have access to it, but whether the parents will be charged with anything is will be up to the Hennepin County Attorney.
