How to Get the Investigators Out of a Cell Cell

Investigators would have to come up with an excuse or a reason they needed to leave. They told greenowalt and a cellmate that a leak behind the wall had developed, but put their recording device near some piping specifically where the conversations could be heard. The ruse worked to get them out of there to place the bug and then get them back in there together. So he was unaware that he had already obtained 8 10 12 hours of this incriminating conversation before he was ever even told there was a liar in the cell.
