John Doe was abducted at his home, murdered in a car, dumped from a dock on a river, and washed downstream to a beach. Which is the primary crime scene?

John doe's home and the dock on a river

Explanation:

Primary crime scene refers to the place where criminal acts are actually committed.

- Even though a criminal act was being done in a car, it can't necessarily considered as a 'place' since it's a moving object.

- Pushing someone from a dock on a river technically couldn't considered as a criminal act unless the push became the main cause of death.

- The beach cannot be considered a primary crime scene since there is no criminal act happening here. The corpse just happened to went to that place.
