Police in San Antonio, Texas, are investigating the possibility of building a criminal case against former Penn State assistant football coach Jerry Sandusky over an alleged offense during a team visit 12 years ago, the San Antonio Express-News reported.

Sandusky, who is charged with molesting eight boys in a scandal that has rocked college football, is accused of making advances on a minor while staying in San Antonio in 1999 for the Alamo Bowl.

"We are investigating the possibility that an offense may have happened while here in San Antonio," police spokesman Sgt. Chris Benavides said in a statement Thursday.

The indictment issued against Sandusky by a Pennsylvania grand jury included claims that Sandusky made advances toward a teenager, referred in the indictment as "Victim 4," who was listed -- along with Sandusky's wife -- as a member of the coach's family party during the 1999 visit.

The indictment claims "Sandusky did threaten to send him home from the Alamo Bowl in Texas when Victim 4 resisted his advances."

"Victim 4," now 27, said he met Sandusky around 13 years ago through The Second Mile, the charity the coach established for troubled boys. He also claims to have been abused several times on the Penn State campus and in hotel rooms in Pennsylvania.

First Assistant District Attorney Cliff Herberg said Thursday that authorities will examine the claims but said it would be the police department's decision whether local charges will be filed. Herberg warned that the passing of more than a decade likely would hinder attempts to bring a charge against Sandusky.

"We've still got to at least conduct the investigation and see what kind of evidence we've got," Herberg said. "We know the same thing that everybody else knows. This is really in the nature of a preliminary inquiry."

The 1999 Alamo Bowl was Sandusky's final game before retirement. He was carried aloft by his players off the field after the victory over Texas A&M.
