The man who police have identified as the suspected shooter is Ian David Long, a 28-year-old Marine veteran who had reportedly been suffering from PTSD.
He shot himself at the scene after carrying out the massacre with a legal 45-calibre handgun, which was fitted with an illegally extended magazine.
Yet before Long's identity was confirmed, numerous conspiracy theorist had begun spreading misinformation that the perpetrator of the attack was a 'Middle Eastern' man.
This appears to have been started by a now-deleted tweet posted by local news anchor Jory Rand who reported that he had spoken to a man who had witnessed the shooting and shooter as "Middle Eastern looking with a beard".
Many of the tweets spreading the false information have since been deleted.
Paul Joseph Watson, a contributor to Alex Jones' Infowars, has doubled down on his earlier tweet explaining that he was only reporting what he had read on the 'mainstream media' and also shared a screenshot of a Google search which showed that Sky News had reported that witnesses to the shooting had described the shooter as 'Middle Eastern'.

Laura Loomer has described the changing of the 'narrative' to be 'strange' as he was originally a 'Middle Eastern man' but is now a 'white marine.'
Pamela Geller, who is a political activist and commentator, and who has previously been accused of spreading Islamophobia, has accused the media of attempting to protect Islam in her coverage of the story.
