The shooting happened near California Avenue and Polk Street after 9 p.m. Halloween night, when a large group had gathered for a vigil and balloon release honoring a woman who died of natural causes.
A 15th person was also hospitalized after being hit by a car, CPD said.
Pierre Riley was struck in the head, his family said, and spent three days fighting for his life before succumbing to his injuries Friday afternoon. According to his family, he had been on life support since the shooting happened and never regained consciousness.
Riley was attending a vigil at the corner that was being held for one of his close friends.
"Everybody around here loved him and liked him," his stepdaughter Artkeshia McGee told ABC7 the day after the shooting.
Police believe they're looking for two suspects who fired shots from a dark-colored SUV. They were last seen driving south on California from the scene.
Police said the shooters appeared to fire indiscriminately into the crowd.
