Crime scene photos typically show spent cartridge cases, their location in relation to body location and provide a depiction of bullet trajectory. From this can be deduced caliber of weapon used, position of shooter and position of victim(s) at time of shooting. Plus a great deal more.
These photographs have historically served of great value in evaluation of crime scenes.

These photographs have historically served of great value in evaluation of crime scenes.

I'm sure they have and they will as technicians at the police crime lab will do a thorough job tracing every bullet to every shell casing to every magazine to every weapo n used, employing a lot of people, and a lot of overtime, and a lot of consultants, and producing a 2000 page report so technical that no one will read it.

But as far as your question: "Where are the crime scene photos? Have they been released?".

They don't release crime scene photos nowadays for numerous reasons.
