DETROIT (AP) — A Detroit grandmother testified Monday that she could only watch in terror as masked police officers with guns drawn stormed her home in a hunt for a murder suspect that led to the fatal shooting of her 7-year-old granddaughter.

Officer Joseph Weekley is charged with involuntary manslaughter in the May 2010 death of Aiyana Stanley-Jones, who was asleep on a couch when police raided the house.

Aiyana’s grandmother, 50-year-old Mertilla Jones, said after a flash-bang grenade exploded through a window she rolled onto the floor and was lying on her stomach facing the door when Detroit special response team members forced their way inside.

“As soon as they came in, their guns were just pointing right there, and he pulled the trigger,” Mertilla Jones said of Weekley. “I seen the light leave out of her eyes and the blood started gushing out her mouth and she was dead.”
