"Then why haven't I been charged with anything?" Pollard asked, to which Harris replied that charges are not always made "right off the bat" during investigations.
"I know you went in there and you killed Kenny," Harris told Pollard. "I know what happened, I just don't know why it happened. Sometimes you get somebody who may have killed somebody or hurt somebody on accident, stolen something, but under the right circumstances it could be explainable. That's why I'm here. I want to figure out what happened.
"I'm telling you, I know it's you. I've got your shirt. I've got your bloody shirt."
Pollard did not admit to the crime during this interview.
Carl Van Fleet, the Ottumwa Cab Company driver who picked up Pollard twice on March 11, 2012, also testified Friday morning.
He first picked up Pollard at 9:15 p.m. at South Ottumwa Savings Bank downtown and took him to Hy-Vee Drug, where they found out it was closed. They then went to the BP across the street and then back downtown.
Approximately an hour later, Van Fleet was called to pick up Pollard again, and took him to 522 Camille St., Pollard's girlfriend's house, stopping at another BP along the way so Pollard could tip him. During this trip, Pollard showed Van Fleet injuries to his head after removing a hat.
