If she is in a rush to check her apartment, she won't follow him to go to his apartment, and she would realize that they went to a different place. She has basic self-defense skill so she could attack him in the car. Since the guy premeditated and waited for a target, he would avoid everywhere installs video cameras and prepare a nearby convict scene (should be a closed space with sound prove and no people often go, e.g., an abandon building, his friends' detached empty house, etc). This scene must be accessible by a car. Draw a circle with its center at the place where she got onto the car, the radius is one or two times the distance to her new apartment. Mark these car paths and suspect areas inside the circle, send trained dogs to trace her smell, look for the area attracting lots of crowns and wild animals. He wanted to kidnap so he prepared food but no icebox. The scene might contain fancy food leftover either on the floor or nearby garbage tush even if he attempted to clean.

Uhhh what? I'm going to assume english isn't your first language, but it seems as if you need to call the authorities instead of 4chan. Could you maybe explain what's going on? Are you trying to find a kidnapping victim?
