Investigators were able to recover the note’s contents after it had been destroyed, the FBI director said, paraphrasing from the note without revealing more details.Authorities said Robinson has not been cooperating with law enforcement. They say that he may have been “radicalised” online and that ammunition found in the gun used to kill Kirk included anti-fascist and meme-culture language engravings.Story continues below this adWhy did Robinson kill Kirk?Though Patel, Cox and others have blamed radicalisation and ‘leftist ideology’, the authorities have not been able to identify what motivated Robinson to open fire at Kirk.While both his parents are registered Republicans, state records show Robinson is registered to vote but is not affiliated with a political party and is listed as inactive, meaning he did not vote in the two most recent general elections.Robinson became a member of The Church of Jesus Christ of Latter-day Saints, known widely as the Mormon church, at a young age, church spokesperson Doug Andersen said.
