Odd Occurrence on Evidence Review on the McInteer Villa Investigation

Audio 12 that was set up in Mr. Cataract's basement area only recorded for 25 minutes. There were new batteries in the recorder (light was still on... on the recorder when we picked it up at the end of the night), the recorder was locked... in case of accidental button push (did not touch the recorder all night. The only time the recorder was handled is when we started it up, placed it, and at the end of the night on pick up, which was 9 hours and 45 minutes later)... and internal storage was not full. Paranormal?... 'shrugs' ... odd?... yup.
