In what has been called the case of the “ginger extremist,” a man has been found guilty of a plot to kill the United Kingdom's Prince Charles and his son, Prince William, so Charles’ second son, Prince Harry, could become reigning monarch of the U.K. Mark Colborne, who is red-haired, wanted a fellow "ginger" to rule the United Kingdom, ABC News reported.

"I would sacrifice my life for that one shot. Kill Charles and William, and Harry become king. Kill the tyrants," Colborne, 37, wrote in a diary. "I want them to see my transition from poor red-haired [victimized] minority that is constantly walked over to a fully transformed military terrorist."

Colborne said at his trial the writings were just angry rants, which he made only when he was not taking medication prescribed for his depression. The judge called the case very strange and said that Colborne was a very strange person.

Colborne said he has felt marginalized because of his ginger hair and compared himself to Anders Behring Breivik, a Norwegian terrorist who killed 77 people in 2011 to end his perceived spread of multiculturalism. Colborne said that he stopped going to classes when he was 13 years old because he was abused in school, forcing him to stay at home with his mother -- a hoarder -- who doted on him, the Daily Mail reported.

Harry is technically fifth in line for the throne. After the current monarch Queen Elizabeth II, her son and Harry’s father Charles is set to assume the throne, followed by Harry’s older brother William. William’s own children Prince George and Princess Charlotte, although only 2 years old and 4 months old respectively, are ahead of Harry to assume the throne, as well.

Before being arrested in June 2014, Colborne had compiled information about explosives and how to make poison from the Internet and books. Colborne’s brother had found his chemicals and papers describing his hatred at their family home in southern England, which led to Colborne's capture by police.
