Correa-McMullen appeared in the movie "Rebound" and had a recurring role on TV's "Judging Amy."
Prosecutors say the 16-year-old actress was killed in 2005 when Watts opened fire on a group of people outside an Inglewood apartment complex. Two men were wounded.
A day before that attack, Watts shot to death 31-year-old Thomas Sanders as he loaded laundry into a car.
Watts was convicted last month of murder with special circumstances, attempted murder and other charges. A co-defendant is awaiting trial.
