A University of Nevada Las Vegas (UNLV) student died after headlining a fraternity's amateur 'fight night' charity event and later succumbing to brain injuries - and now his family is demanding answers.
Nathan Valencia, 20, collapsed about five minutes after participating in 'Kappa Sigma Fight Night' on November 19 and was rushed to the hospital.
Doctors confirmed the college junior was suffering from internal bleeding and brain injuries after being severely hurt in the fight.
Valencia passed away on November 23, just days before his 21st birthday. His organs were donated to eight different people, The Sun reported.
The kinesiology student, an active member of Sigma Alpha Epsilon at UNLV, registered for the charity event despite having no boxing experience.
