Ex-CMU teacher admits to sexually abusing child

MOUNT PLEASANT, Mich. (AP) — A man who taught journalism at Central Michigan University has pleaded guilty to possessing child pornography and admitted that he sexually abused a child three times a week between 1995 and 2002.

The Michigan State Police Mount Pleasant Post said Tuesday it’s helping the United States Secret Service in an additional investigation involving a possible victim of Mark Ranzenberger, who pleaded guilty the same day in federal court in Bay City. Ranzenberger faces many years in prison.

The investigation began when pornographic images were mistakenly displayed in class with his computer. Ranzenberger was accused of possessing 1,000 images of child porn. He told investigators that he thought “he had gotten rid of all that stuff.”

In March, he quit his job at CMU with a handwritten note. He also quit the Mount Pleasant Planning Commission. Ranzenberger was a journalist at the Morning Sun in Mount Pleasant until 2013.
