Metro Nashville Police Officer Andrew Delke is back in court today for the third in a series of hearings leading up to his murder trial next month. His attorney has called multiple witnesses and introduced new evidence to try to prove his shooting of Daniel Hambrick in 2018 was justified. WPLN's Samantha Max has been following the proceedings. She says they've focused on two issues that are likely to play a central role at trial: whether Delke had the right to shoot and a missing piece of surveillance footage. She sat down with Morning Edition host Nina Cardona to discuss the latest news from court.
