Over $600,000 has been raised for the families of the three men who were stabbed while defending a Muslim teenager and her friend on a train.

In a hate crime which occurred in Portland, Oregon on Friday, Taliesin Myrddin Namkai-Meche and Ricky John Best were killed and Micah David-Cole Fletcher was severely injured.

It happened as a man launched into a verbal tirade against the teens, one of whom wearing a hijab, while saying “all Muslims should die”.

The suspect was identified as Jeremy Joseph Christian, a 35-year-old man, and was later arrested. He is due to appear in court on Tuesday.

Christian is charged with two counts of aggravated murder, attempted murder, intimidation and possessing a restricted weapon.

The three men have been hailed as “heroes” in their local community as well as across social media.

Destinee Mangum - the 16-year-old who was travelling with her friend, 17, also hailed the three men who protected them.

“I just want to say thank you to the people who put their life on the line for me, because they didn't even know me and they lost their lives because of me and my friend and the way we look,” she said.
