Shannan was a frequent Facebook live-r and posted pictures of her family almost daily.
This gave directors hours of footage about Shannan talking about her life.
Instead of surviving family members telling her story for her, she told the story herself.

You see the potentially forced selfies of Shannan and Chris on their family vacation.
Its eerie to see a woman cheek-to-cheek with the man who would kill her days later.
These texts popped up on the screen just as they would pop up on a phone.

There were even texts from Chris that he sent after he killed her asking her where she was.
As if he didnt just bury her hours earlier.
The icing on the creepy cake is the footage from the police.

The beginning of the documentary shows body cam footage of the police arriving at Shannans house and interviewing Chris.
Before they leave, the neighbor pulls the policeman aside to tell him that Chris is acting strangely.
Police also provided footage of the actual interrogation, court, and sentencing process.
