Prosecutors contend the men fired into a South Los Angeles backyard they mistakenly believed belonged to a rival gang. Five-year-old Aaron Shannon Jr. was shot in the back of the head Oct. 31 as he posed for photos in his Spider-Man costume. Two relatives were wounded.

Authorities say the victims had no gang ties.
