They feed him on the details of what they further discovered.
They got to the part where he left his home around 7:30pm on the day of his death. He looked so excited in the CCTV feed and again he vanished.
Someone tampered with it again. They spent a lot of time retrieving the field but again, only he saw what he saw.
It was an alley, which he was caught entering as if tracking someone and he never came out, but somehow he was found dead at his house, yet no records about how he got home.
The family were probably used to his coming home late and concluded that he came home when they were asleep.
The man saw something and being someone whose line of job is investigating, he probably tried taking a picture or recording of what he saw.
Brian was deep in thought.
"How about we check out that alley and trace back to all the possible exit he must have taken to escape?" He asked.
That venue isn't far from the spot Hannah was found dead.
