Mistrial Declared In Case Of South LA Boy Murdered On Halloween 2010

LOS ANGELES (CBSLA.com) — A mistrial has been declared in the murder case against a man accused of fatally shooting a 5-year-old boy wearing a Spider-man costume on Halloween 2010.

Leonard Hall, 24, faced one count of murder and two counts of attempted, willful, deliberate and premeditated murder in the death of Aaron Shannon Jr.

The jury Friday told a judge that they voted nine to three on all counts.

"If think the system is fair, it works for everybody. The wheels of justice just turn slowly," William Shannon, the victim's grandfather, told CBS2's Dave Lopez despite Friday's outcome.

Prosecutors claim Hall and accomplice Marcus Denson, both alleged Kitchen Crips gang members, fired at least seven shots into the backyard of a home in Florence, hitting Shannon once in the head.

Denson and Hall were reportedly instructed by another gang member to go into enemy territory in search of a rival gang member and to "take care of him" when the shooting occurred.

Denson pleaded guilty to manslaughter in connection with Shannon's death.

A pre-trial conference has been scheduled for May 9.
