It happened some time around 11:30 p.m. in the 400 block of St. Charles Dr. in Barrett at a home where the boy had been visiting.
An adult at the home had left the 16-year-old inside while he went to get food. When he returned, he found the boy had been shot, according to the Harris County Sherrif's Office.
