CSI: Crime Scene Investigation, Season 9

Grissom:
You think that they shot each other

Riley:
Why not? There's motive. The evidence suggests it.

Grissom:
Where are their guns?

Riley:
Dead man with a gun in the hood, gone in sixty seconds. Jin skips town because this family dispute uncovers his once invisible gang. He leaves the booby trap because he's angry about it.

Grissom:
It's possible. It's also possible that Jin shot both vics. Which is what the kid said and he was the closest witness.

Riley:
If your uncle and your mother shot each other, you would probably blame the gang banger too.

Grissom:
Okay, pilgrim. We'll settle this on the street.
