Thirty-five-year-old Eric Floyd and 41-year-old Levon Warner could face the death penalty if convicted of first-degree murder in the May 2008 death of Sgt. Stephen Liczbinski. The alleged gunman, Howard Cain, died in a shootout with police.
Authorities say the three men were fleeing police after robbing a bank.
Prosecutors on Tuesday called Liczbinski's widow, Michelle, as their last witness.
She told jurors her husband gave her a kiss and said he loved her before he left for work on the day he was killed.
Defense attorneys are now expected to begin telling Common Pleas Judge Renee Cardwell Hughes how they will present their defense.
