SOUTH BEND – A former custodian at a northern Indiana high school was sentenced Friday to 15 years in prison for placing a camera in a boys’ locker room shower.

Robert Troup, 54, of Mishawaka pleaded guilty in November to enticing a minor to engage in sexually explicit conduct to produce pornography, a federal offense. The camera recorded 43 boys, according to police. There is no evidence the images were distributed.

A prosecutor said the government settled for a sentence slightly below the minimum recommendation because it wanted to spare victims the pain of testifying if the case went to trial.
