Stanley Ross White III of Bloomington was arraigned on one count each of murder and attempted murder, according to the Los Angeles District Attorney's Office.
Prosecutors claim on April 1 victim Denise Chiffon Berry, 44, drove up to a Hawthorne police officer near Kornblum and Rosecrans avenues saying she was being followed by a vehicle driven by the defendant.
While Berry was parked in front of the officer's patrol vehicle, White's vehicle pulled up and Berry and her son were shot, prosecutors say.
The boy survived multiple gunshot wounds and has been interviewed by investigators, Los Angeles County Sheriff's Department detectives said earlier this month.
Prosecutors claim Berry and her son had encountered the car that followed them earlier and had looked at the occupants of the vehicle.
White is scheduled to appear in court May 13. His bail is set at more than $2 million.
If convicted as charged, he faces a possible maximum sentence of 33 years to life in state prison.
