NEW BRAUNFELS, Texas -

Autopsies have discovered that a sophomore at Canyon High School died of blunt force trauma to the head that led to bleeding in the brain.

Officials say Logan Davidson was walking out of class when he was suddenly punched in the head twice, causing him to hit the wall behind him.

According to officials, the teen was rushed to a hospital, where he later died.

Police have arrested a 15-year-old suspect on suspicion of aggravated assault. Authorities are withholding  the suspects name because of his age.

A vigil for Harrison was held Thursday night.

His funeral has been scheduled for Monday at Oakwood Baptist Church.
