CLEVELAND -- The jury has been sequestered after not reaching a verdict after three hours of deliberating the case involving the slaying of a Cleveland police officer. Deliberation will resume Tuesday morning.

Lamidi Kafaru faces seven charges in connection with the slaying of Officer Derek Owens.

Closing arguments were held Monday morning after 250 exhibits were shown and 20 witnesses testified.

Kafaru, 19, faces the death penalty if he is convicted of killing Officer Derek Owens.

Prosecutors said Kafaru fired the gun that killed Owens several months ago.

On Friday, Kafaru testified in his own defense.

Days after the shooting, police found the .44-caliber revolver used to kill Owens hidden in a bathroom light fixture in Kafaru's house. Kafaru said he was framed by Anthony "Googie Man" Milner -- a friend from the neighborhood -- who sold him the gun the morning after the slaying.

But Milner, who testified last week and was called back to the witness stand Thursday, said he, Kafaru and another young man from the neighborhood were drinking beer on the porch of an abandoned house on Parkview Avenue when they saw the police and ran.

Milner said he gave the cops the slip and made it across the street. It seemed the officers had cornered Kafaru in a front yard when Kafaru pulled a gun from his waistband and fired at them, Milner said.
