In the opening scenes, Rusty calls 911 on a cell phone. Rusty throws the phone into into a metal 55 gal. drum. You can still hear the operator talking, asking if anyone is still there. A metal drum is effectively a Faraday cage, meaning a radio or microwave signal would be completely blocked.
When Brenda Leigh bought the house of the prostitute that was killed (#1.3), that home's address was 707 Edgemere. In this episode, when Stroh is shot, the address given for the scene, Brenda Leigh's home, is 3882 N Ridgecrest.
However, Brenda and Fritz moved in to the Ridgecrest rental at the beginning of the fourth season.
