1. A blind man as an accountant - suspicious.
2. If she was stranded, why did they have to canvas a 10 block area for her. She would have stayed in the same place - suspicious.
3. If bourbon does freeze as Artor states, the verbiage says it was just 'beginning' to crystalize - suspicious.
There is evidence that all 3 could have been the lookout.
Maybe the police should have looked for the other walkie-talkie.
