US federal officials have confirmed that they are opening an investigation into the Oklahoma school district where high school pupil Nex Benedict died following a fight last month. Nex Benedict, who was Two Spirit/gender non-conforming and used he/they pronouns according to his friends (as confirmed in this NBC interview), died on 8 February, one day after telling his family they had been involved in a physical altercation in the toilets at Owasso High School. Owasso Public Schools have faced criticism for not reporting the fight to police or seeking emergency medical treatment for Nex Benedict in the aftermath of the altercation.
