Jurors are deliberating for another day at the trial of a rookie New York City police officer who fatally shot an innocent man in a dark public housing stairwell.

Deliberations resumed Thursday at the trial of Officer Peter Liang (lee-ANG').

Wednesday was the first full day of deliberations. Jurors asked to rehear testimony from Liang and other witnesses.

Liang says he accidentally fired the gun after being startled by a noise while patrolling the stairwell in 2014. Prosecutors say he was reckless and did little to help the dying victim, Akai (ah-KEYE') Gurley.

Gurley was taking the stairs with his girlfriend instead of waiting for an elevator.

Liang faces up to 15 years in prison if he's convicted of manslaughter and other charges.
