Answer:
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.
