The incident occurred around 1 a.m. when 19-year-old Griffin Healey fell from a second-story balcony at the Lambda Chi Alpha house on Colorado Street.
Witnesses told Pullman police that Healey, a member of the Lambda Chi Alpha fraternity, was trying to sit on a railing when he lost his balance and fell backwards, landing on his head.
Officers say Healey was unconscious but breathing when they arrived on scene. Police confirmed alcohol was involved.
Healey was taken to Pullman Regional Hospital and then transported to Sacred Heart.
This is the fifth time a college student has fallen from a building on the Palouse this year, the fourth involving a Washington State University student.
