Additionally, Robert Zanolla, is charged with felony conspiracy and criminal use of a communication facility and related misdemeanors.

Eight more "student-aged defendants" charged are facing misdemeanors for possession and paraphernalia, the AG said. Those include Liam Smith, Michael Brogno, Kaden Howe, Connor Hurleigh, Seth Beardsley, Kyle Ridpath, Daniel Price and Charles Wiseman.

The AG's office confirmed at least four of the men charged are current Penn State students.

"This was a coordinated and highly-profitable drug-trafficking crew revolving around two senior members of the fraternities, other fraternity brothers, and pledges," Attorney General Sunday said. "In fact, according to the evidence uncovered, cutting and packaging cocaine was, for some pledges, an indoctrination into the fraternities."

Thomas Robinson's father, Paul Robinson is charged with felony tampering, hindering apprehension for taking steps to conceal evidence and obstructing the investigation.

Penn State University confirmed to Fox News Digital that the university has responded to the criminal allegations and announced the Delta Upsilon fraternity would be placed on interim suspension while the school investigates. It also made note that Sigma Chi is "not a recognized organization and operates outside of the University's support and oversight."

In a statement, Penn State said in part:

"We are horrified by these serious allegations against current and former students," said Andrea Dowhower, vice president for Student Affairs. "Criminal activity, including hazing, such as this has no place at our institution, and we will cooperate with law enforcement in any way we can. We will continue to enhance our efforts around health and safety and hazing educational efforts for all our organizations."

In a statement sent to Fox News Digital, Delta Upsilon Executive Director Justin Kirk said, "The charges filed today [Monday] stem from alleged incidents that Delta Upsilon International Fraternity was previously made aware of. The individuals associated with Delta Upsilon have either been expelled, suspended or resigned. We will continue to work closely with the university on any investigative efforts."
