"Please pray for my family," says Pam Davis whose 5-year-old niece accidentally shot and killed herself with her grandmother's old revolver.
Detroit Police say little Mariah Davis found the gun under a pillow and took it to another room where she had been playing with her younger brother and a neighbor's child.
The child's fatal shooting took place in her grandparents' house on Detroit's west side, where Mariah's grandmother was babysitting the three children.
"Mariah accidentally shot herself in the neck," say police.
The other children were not injured.
Mariah's grandfather tells 7 Action News that the gun was his wife's after it had been passed down to her by her own father.
Detroit Police are continuing to investigate. And when the investigation is complete, police will turn their findings over to prosecutors for review.
