If someone told you a story about a couple who went travelling across the country, the guy with a history of being controlling and jealous, the girl seen to be crying uncontrollably when they are stopped by police after a domestic disturbance that became physical, and then the guy suddenly arrives home without the girl, no one can contact or find her, he lawyers up and won’t speak to police before disappearing himself, and then the girl’s body is found back near their campsite… would anyone really say “gee I wonder how she died, maybe an accident?”
JMO he’s running due to not wanting to face the consequences of his actions.
