Three people were arrested in connection to the killing following the raids, according to Mayor Garcetti.

Diaz was eating at a taco stand with his girlfriend and her two brothers at the time of the shooting. He asked the group of taggers to stop, that's when the group claimed their gang involvement, officials said.
