STILLWATER, Oklahoma - A student was found dead Saturday inside an Oklahoma State University fraternity house, police said.

About 1:30 p.m., police were called to the Sigma Chi house, 1101 W University Ave., in reference to an unresponsive person.

Police found Brandon Matthew Cavazos, 20, of Bedford, Texas, dead inside his bedroom. Cavazos was a member of the fraternity.

Friends told police they called 911 after finding Cavazos in his bed and unresponsive.

Police said there were no signs of trauma or foul play at the scene. 

They are investigating the death as an unattended death. The medical examiner will determine a cause of death.

This is not the first time police investigated a death at Sigma Chi. In October 2012, a 22-year-old man, who was a member of the fraternity, was found unresponsive. The junior died the next day as a result of alcohol and heroin poisoning, according the medical examiner's office.
