HARRIS COUNTY, Texas -- A 4-year-old girl died after she was accidentally shot by her 3-year-old sister in a Houston-area home, officials say.
The shooting happened Sunday evening at an apartment complex in northwest Harris County, according to the Harris County Sheriff's Office.
Investigators believe the two sisters were home in the apartment with five adults, including their mother and stepfather.
The adults believed at least one of them was watching the girls, when they were in fact unsupervised in a bedroom, according to Sheriff Ed Gonzalez.
Somehow the 3-year-old got a hold of a loaded semi-automatic pistol and accidentally shot her 4-year-old sister.
