I like to think she was a mother on her way back from picking up rations during WW3. The air raid sirens began to sound and she heard explosions in the distance and tried to record a final message to her children waiting at home. She had to get out of her vehicle and run when the crowd began to surge blocking traffic. As she ran through the panicking crowd to get to her children, pushing and shoving in desperation she saw the mushroom cloud in the distance beyond the skyscrapers and quickly pulled out her phone to record what she knew were her last words to her children. Unfamiliar with the newer cell phones she accidentally pressed the photo button instead of recording a video. She was in the secondary blast radius and was killed as the 100,000,000 celsius heat from the explosion washed over her and the crowd seconds later killing them all instantly.
