Caroline had received formal military education since she was young. It was impossible for her to let her partner get into trouble. Hence, after hesitating for a while, she decided that she couldn't leave it alone.
She knew that there were surveillance cameras in Will Sr.'s store, so she thought of a way to hack into the computer that Will Sr. had left in the store. She saw the scene of Will Sr. being coerced and captured.
Then, from the corner of the surveillance camera at the entrance of the store, she saw Will Sr. being stuffed into a black car. Unfortunately, the car was parked in the corner of the surveillance camera, so she couldn't see the license plate number.
Caroline could only pull up the traffic routes in this area and find the surveillance video of the intersection. She calculated the speed and time and roughly determined which car it was. She also obtained the license plate number and followed the car's traces the entire time.
