Aiyana Stanley-Jones Update: Deliberations begin in manslaughter trial of Detroit cop in death of 7-yr.-old girl

A Wayne County judge gave final instructions and sent the jury behind closed doors at 10:15 a.m. Friday.

Weekley is charged with involuntary manslaughter in the death of Aiyana during a raid in May 2010. He told jurors that he was struggling with Aiyana's grandmother when the weapon accidentally discharged.

The jury could convict Weekley of involuntary manslaughter or reckless discharge of a firearm, a misdemeanor. He also could be acquitted.

Prosecutor Rob Moran says there was no interference from grandmother Mertilla Jones. But defense attorney Steve Fishman says Jones has no credibility because she's told different stories about what happened.

A stun grenade, which emits smoke, a bright light and vibrations, was thrown through a window before Weekley's Special Response Team entered the home. The raid was recorded for a police reality TV show, "The First 48," and some video was used at trial.
