Richard's story still doesn't explain how the kidnappers knew that Heller and Audrey would be at Richard's that morning.
Maybe Richard talks in his sleep.
He didn't know he was set up, nor did he know that the couple KNEW who he was. So, in the throws of passion, he mentions going to see his dad. Bingo. Many makes the call from Richard's phone to Marwan.
it allowed a phone "tap" apparently.
they are headed to an apartment now with the "couple".
Actually it does. Edgar says later in the show that when they used his phone to make the call to Marwan they installed a snoper program that allowed them to monitor all of his calls. So they knew that he had spoken to his dad and that he was going to visit.
