The case of a decades-old Long Beach gang killing ended in a mistrial Friday when jurors deadlocked 8-4 in favor of finding the defendant guilty.

More than two decades after a shooting left a 26-year-old man dead at the end of a Long Beach alley, prosecutors say they have enough evidence to convict the man they believe pulled the trigger.

“Let’s just say I don’t expect him to reach his minimum parole date before the expiration of his life,” the judge said in court.

Daniels became “agitated” when he saw his girlfriend’s estranged husband spending time with his girlfriend’s 6-year-old son outside and shot him in front of the boy, prosecutors said.

On the first day of trial Tuesday, prosecutors brought multiple witnesses to the stand who described the events leading up to and after the shooting death of 38-year-old William Hayes on April 19, 2017.

Jurors decided the two weren’t guilty after defense attorneys argued the evidence showed they weren’t the gunmen.

In their opening statements, attorneys for the defendants told the jury that they had just been at a party with about six other friends on the night of the killing.
