Prosecutor says Detroit police officer made key errors in raid that killed 7-year-old girl

A prosecutor says a Detroit police officer made critical errors during a raid that led to the fatal shooting of a 7-year-old girl.

Jurors have heard opening statements Monday in the involuntary manslaughter trial of Joseph Weekley. There's no dispute that he fired his gun, striking Aiyana Stanley-Jones in 2010.

Assistant prosecutor Rob Moran says Weekley hesitated at the door instead of charging into the house to hunt for a murder suspect after a stun grenade was fired inside. Moran says an officer in that situation isn't supposed to stop.

Defense attorney Steve Fishman says Aiyana's death was a tragic accident. He says Weekley pulled the trigger when the girl's grandmother reached for the gun.

Police were accompanied by a crew from a reality TV show, "The First 48."
