DETROIT -

Jurors in the trial of a Detroit police officer were driven to a house Wednesday for a demonstration of a "stun grenade."

Officer Joseph Weekley is accused of manslaughter in the May 16, 2010 shooting death of 7-year-old Aiyana Jones. Weekley and other members of the Special Response Team raided the home she was visiting in order to arrest a murder suspect. Weekley fired a shot three seconds after the stun grenade detonated.

The jurors crowded into a living room, similar in size to the 14-by-13-feet room in which Aiyana was killed. They were given safety glasses before a police officer detonated the device on the floor.

The few jurors who were visible to reporters appeared to wince, but had no strong reaction. The stun grenade, with 174 decibels and a bright light, is designed to disorient unsuspecting people for several seconds.

During the raid, the device exploded on the same couch where Aiyana was sleeping with her grandmother. The grandmother denies Weekley’s statement that the gun fired after she grabbed it, or hit it.

Closing arguments in the case are expected on Thursday.
