The way I read it, gang member Gerardo Diego Ayala was killed by a police officer. Then Victor Sanchez and 2 unidentified subjects fled the scene in a car. It's unclear what "officer involved shooting" means, but that's how I took it...

That is what "officer involved shooting" normally means — a cop shot them.

In the US this means the fleeing are accused of murder, right?

Quite possibly felony homicide (ironically). And not just the US, any common law country (e.g. most commonwealth countries).
