On the day when Meaghan Bosch’s cause of death was made public, her father challenged university officials to do something about the drug problems on campus.

“The administration is either unwilling or has been incapable of addressing this issue, and we urge the administration of the university to radically change their approach to this problem,” Joseph Bosch said at a Monday news conference held at Dallas Police headquarters.

He specifically mentioned the Greek system as a group with drug issues.

“Drugs are woven into the Greek system and the social fabric of the university,” he said.

Bosch was the third SMU student to die during the 2006/07 school year.

The Texas Rangers, who are assisting in the investigation into Bosch’s death, said she died from an accidental overdoes of cocaine, methamphetamine and oxycodone. Oxycodone is used as a respiratory depressant, but can be addictive.
