The most recent message was found Friday by freshman Carlos Barbosa Jr. He says it’s the second racist note he’s found this year and the school needs to take a tougher tack against harassment.

A university spokesman says administrators are “disappointed and disgusted” by the notes. He says the school is offering a $1,000 reward for information that identifies the person responsible for any of the messages.
