Can new athletic director help Penn St. move on?

There were new developments Friday in Penn State sexual abuse scandal. The son of recently fired head football coach Joe Paterno has lung cancer, according to his son, who says it's a treatable form of the disease. Meanwhile, there's a new man running the athletic department, as CBS News correspondent Armen Keteyian reports from State College.

Dr. David Joyner -- ex-Penn State football player under Joe Paterno, star wrestler and university trustee since 2000 -- was officially introduced Friday as the school's acting athletic director, as a wounded university tries to move forward from the sex abuse scandal that has devastated the community.

"You are an insider at Penn State. What assurances can you give what critics have called a culture of denial at Penn State will not continue?" Keteyian asked Joyner at a press conference.

"No matter what they say about me being an insider," he answered, "as you watch what I do, and watch how this university behaves, you will know and appreciate that I am about doing the right thing."

Penn State's board of trustees has "complete responsibility" over the university. Yet Joyner said, to his knowledge, the board was never informed of multiple allegations of sexual abuse by former football coach Jerry Sandusky until news of a criminal investigation broke in March.

"If President Spanier knew in 2002 certainly of that incident, why wasn't the board informed?" Keteyian asked Joyner.

"I don't know the answer to that question."

Fallout from the charges of abuse -- and a potential cover-up -- has now cost four top university officials their jobs, including Paterno, the larger-than-life coach, and school president Graham Spanier.

On Friday, the NCAA announced it would examine what it called the "actions and inactions" of university personnel. In a statement the organization said: "It is critical that ... the how we constrain or encourage behaviors that lift up young people rather than making them victims."

A spokesman told CBS News the inquiry will focus on ethical standards.

In a related development Friday, the Second Mile charity is preparing to fold. The charity was founded by former coach Jerry Sandusky, the man at the center of the sex abuse allegations. Prosecutors allege that Second Mile was used in part to funnel abuse victims to its founder.
