The well armed rogue took the phone. "Thank you. I expect a trap as well. Unless you have a computer with net access in the bar... I'll be back shortly. Don't go anywhere." Stepping out he vanished into the night.

Back on his hidden motorcycle, Mithias had well... a computer. Connecting the phone and running some hacked police software he came up with a map of the phone's whereabouts for the last multiple days. Simultaneously searches were run on the numbers the phone had called and where those phones were located at the time of the call, but the results would take some time to come back. He'd get a text. Until then, he'd hold into this phone. The kidnapper-slash-torturer might call again. 

About twenty minutes later, Mithias reappeared at the Tortuga. Shifty-eyed, he entered, then found Trixie and Alister Still at the bar. "Look" He came over, holding a flat-screen phone. These are the locations frequented by your Adelisa. I suggest we take caution in patrolling these areas. They could be where Maria is kept, but they could also be irrelevant. Our enemy may expect us to be looking there. I will have more information soon, but my software takes time to run its iterations. I will keep you informed." Seeing Alister and Trixie looking unsettled, he continued. "Let me start at this location, by the docks. I will not be discovered. I suggest you two stay together, if you are planning on going out to investigate."
