Barry's Confession to Suzanne's Murder

Barry told police he and his brother went drinking at a pub before returning to their sister's home where they were both staying. Barry said he went to bed around midnight and didn't get up until early the next morning. His sister verified this alibi. She had stayed up until two a m and didn't recall seeing barry leave the house at any point. There was nothing unusual about his appearance or demeanor. He hadn't noticed anything unusual when he visited on wednesday night, nor had he heard gregory crying. And it seemed a bit strange that he wouldn't have checked the entire house if he was that worried about suzanne.
