However, the Echo speaker was reportedly streaming music near the tub, and investigators believe it could have been awakened intentionally or accidentally. If so,the presence of a recording could tell them if Bates was awake when he said he was sleeping, for instance. It only sends data after hearing its wake up words, just like everything else. If it were constantly streaming they would be caught as soon as someone decided to fire up wireshark (i.e. very soon after release.)
