Both the prosecution and defense teams rested their cases. The judge is expected to give instructions to the jury Friday morning.
The jury went on a field trip Wednesday to see a flash grenade detonated.
The demonstration was made to mimic a flash grenade used during the raid on a Detroit home that killed 7-year-old Aiyana Jones. It's designed to disorient people with a blinding light and a loud noise.
Officer Weekley's defense claims Aiyana's grandmother hit Weekley's gun, causing him to accidentally pull the trigger.
Accompanying Detroit Police on the raid were producers from the A&E show "The First 48."
Wednesday, the prosecution and defense agreed; Officer Weekley's DNA or fingerprints were not found on his own gun or his protective shield.
