"But it was on the day the ring was made that she encountered a severe car accident on her way back to the company. The driver caused the accident and fled the scene immediately. A passerby later reported it to the police. By the time the medical staff arrived, she had already missed the golden hour for rescue and died without responding to treatment."
"Later, the traffic police investigated the scene of the accident and found that the offending vehicle was speeding and there were no brake marks at the scene. Upon inspecting the vehicle, they found no faults with the brakes."
"No objects that could identify the driver were found in the car, not even fingerprints could be extracted."
"That is to say, this car accident was not an ordinary traffic accident, but a premeditated murder."
"All the design drafts in my sister's car, the finished ring, and all relevant documents, disappeared without a trace."
