"We start with the call?" Dan Mills guessed.
"Yes," Cruz replied. "Let me get Garcia in here. She can begin by isolating the background noise as well as trying to find a match to the voice pattern." He took out his cell phone and pushed a button.
Rossi, meanwhile, was repeatedly shaking his cell phone and then checking the screen. "That's strange," he commented. "Reid didn't answer his phone and he isn't calling back. That's not like him. Let me try Emma."
He pushed another button, waited, and then spoke into the phone. "Emma, it's Dave, please call me."
"Maybe they are – you know - busy," Agent Mitchell grinned at him. "After all, they are married."
"It's not like that – " Rossi began. He was interrupted by Garcia bustling into the conference room and taking a seat in front of the recording equipment.
"Okay, let's see what you have," she said as began pushing various buttons.
It didn't take long before the group was listening to the sound of passing vehicles that had been extracted from the background of the phone call.
"Sounds like – " Cruz hesitated to think.
"It seems to be echoing off a low roof," Agent Mitchell observed.
"A parking garage?" Rossi suggested. "There are enough of them on the strip. Every hotel has at least one."
"Or at the airport," Cruz pointed out. "How close is the nearest one to this building?"
"Less than a block," Frank Caldwell told him. "You can see right into it from our front door."
"That's how whoever this is knew that the envelope had been delivered," Cruz realized. "They were probably standing in the garage watching."
"Add about fifteen minutes for the guard to clear it, and then call," Agent Grant exclaimed.
Rossi was again shaking his cell phone and then looking at the screen.
"Sir?" Garcia asked.
"Neither Reid nor Emma have returned my call," Rossi worried. "Garcia – Can you?"
"Track their cell phones? Of course, Sir," Garcia replied as she moved over to an unused computer sitting at the end of the table and attacked the keyboard.
"And, I'll get Kevin started on the security cameras from the parking garage," Cruz decided.
"Oh – Oh!" Garcia looked up from her computer screen.
"Not good?" Rossi guessed.
"Not good," the tech confirmed. "I have located both of their phones in the general area of what appears to be a strip mall just off The Strip."
"My rental car?" Rossi questioned.
"Same place," Garcia told him. "And, it appears it hasn't moved for a while."
"What is in the strip mall?" Cruz questioned.
"A coffee shop," Garcia told him ruefully. "That must be why they pulled in there. Reid was probably going through caffeine withdrawal."
Cruz looked over at Agent Mitchell. "You have some agents available to go take a look?" he questioned.
"They are on their way," Agent Mitchell nodded to Agent Grant, who pulled out his cell phone and began pushing numbers.
