Watch He Walked by Night

Late one night, a Los Angeles police officer is shot and killed. Two of his fellow officers pledge to bring the shooter to justice in order to avenge their friend's death. Unfortunately, they don't count on the cleverness of the perpetrator as he avoids all their best efforts. The case takes a turn for the better as the shooter slips up on a few key pieces of evidence, potentially leading to his own arrest and long-term imprisonment.
