Let's review, Chuck.
You got an e-mail from the killer.
Then you did the laser puzzles.
Then you get a phone call from the killer (this should place the phone number or the name of the killer in your call back cellphone).
You hide from the killer.
You then prepare the trap for the killer.
---Move as close to the fence at left before you use the smartphone.
Then open the e-mail and scroll down. The scroll on the right side is icky. So be sure that yous o scroll. The killer should be listed there and you can call him after you prepare the trap.
Be sure that you did the trap correctly:
Place the keypad and the remote control on the panel.
Then code the remote control.
Take the remote control.
Key in the keypad; press OK - then move to the fence.
