2nd person charged in death of professor found in quarry

George Ishler Jr., 39, of Pennsylvania Furnace, had previously been charged with first- and third-degree murder in the death of Ronald Bettig, 56, an associate professor of media studies whose remains were found last week.

The two told police Aug. 15 that Bettig and his vehicle had been missing for three days and suggested that he may have gone to California, authorities said in court documents.

According to Penn State's website, Bettig joined the College of Communications in 1988 and was an associate professor of media studies.
