This is one of the best reports I have read so far:
Authorities are exploring evidence that Nashville, Tennessee, bombing suspect Anthony Quinn Warner was interested in various conspiracy theories
Some writings found by investigators believed to be associated with Warner, who was killed in the Christmas Day RV explosion, contain ramblings about assorted conspiracy theories, sources said.
Multiple law enforcement sources also told ABC News earlier this week that investigators looked at whether Warner had paranoia about 5G cellular technology.
Investigators are continuing to analyze chemical residue from the scene and are working to narrow down the chemicals that were likely used to make the explosive device.
They are also looking into how the suspect allegedly acquired the bomb-making materials to ensure there were no accomplices.
Sources told ABC News that receipts and credit card account information indicates Warner allegedly purchased items that could be used to construct a bomb, though they cautioned that certain common chemicals have uses that could have nothing to do with bomb-making.
The 5G cellar theory as a motive seems to be the best match for the publicly available evidence.
