A George Mason University student who died after he ran through a fifth-floor window was identified as 19-year-old Tristan Medina from Spotsylvania County.
Authorities believe Medina may have been under the influence of a drug when smashed through his window and fell to the ground.
Police are still trying to find out which drug Medina may have taken. Other students may have the drug and be at risk, police said.
Students told police the student was on a "hallucinogenic substance" when he ran through the window at the Potomac Heights Residence Hall, a university spokesperson said.
Officers arrived and found him on the ground about 4:45 p.m. Saturday. The sophomore student was still alive but wasn't responding, the university spokesperson said.
Medics took him to a hospital, where he was pronounced dead, according to the spokesperson.
Investigators said no foul play was suspected, but they were told other students may have the same substance in their possession and could be at risk.
The university maintains a medical amnesty program. If a student has taken the substance and fears for their safety, they can contact the school’s police department for help.
The night after he died, members of Medina's fraternity, Sigma Alpha Eplison, held a vigil in his memory, the school's newspaper reported.
Medina was also a standout football player at Massaponax High School.
