It was dark and blunt so they could not see the video clearly, they both were trying to figure out as something was moving.
As it was a blunt turn, there were no cameras in those places.
They could see a car going towards the other side of Jeju Island.
As they couldn't see anything except the moving car, Ryan was helpless as it was difficult to trace anything. Then he got an idea and asked the ex detective that:
"Sir, this is her mobile number can you trace her last location"
"Ryan, Vivian's number is dead now and the last location was in the middle of the road, after that no signal could be traced".
"If the signals stopped here means something happened here and there is something connected with the moving car. Maybe her car was going towards the town, maybe she was helping someone. There is a medical college and a hospital nearby. You can go and search there" he analysed.
