Braylon Ken Yeng Houa Chang
A gun left in his reach
He was a twin, a child of a Vietnamese family living in Michigan. His father came to visit them from Wisconsin. The father brought a gun.
His 8-year-old brother found the gun on a pool table in their home and showed it to the father, who then tossed it on his bed. Afterward, the father went to the bathroom, leaving his children unattended in the basement.
