Police said the woman told them she was driving north on Atlantic Avenue in North Long Beach when someone shot at her car.
The suspect, only described as a white man between the ages of 30 and 35, was last seen fleeing on foot, police said.
The man was hospitalized after officers found him, and the shooter was at-large, according to authorities.
A man and a woman were wounded in the large fracas on Paramount Boulevard just north of Candlewood Street Tuesday night, police said.
Investigators now suspect the gunfire was from two different groups targeting each other, in a situation that likely had nothing to do with the officers.
“Woke up to a big surprise!” She wrote on Facebook. “Happy 5th of July Wrigley! This could of hit any innocent person!”
The men were in an alley behind a home on 14th Street near Raymond Avenue around 11:30 p.m. when the gunman fired, police said.
