Claire Pec Sapon, an employee at Juicy Box, said she was working in the back with her manager when about 20 people suddenly rushed into the kitchen.

"All I hear is run, run, run," Sapon said. "I was scared, honestly. I was thinking about calling my loved ones, thinking what was the next step to do."

Argument started over a dog 

The backstory:

According to the Houston Police Department, the shooting started after an argument over a dog.
