City News Service reports the violence unfolded after Long Beach officers were flagged down at 2:30 a.m. Wednesday.
Long Beach Deputy Chief Robert Luna says a woman reported that an armed man had made death threats against her and her family.
Luna says a Los Angeles police helicopter crew then spotted a man believed to be the suspect at a gas station in Carson, but arriving police units were met with gunfire.
After an exchange, the suspect ran off through a park and more shots were fired.
Luna says the man then ran into a neighborhood and tried to break into a residence but was shot.
