FRAMINGHAM (AP) — A Massachusetts university is now offering a $5,000 reward for information as part of its investigation of a series of racist messages found on campus.

Framingham State University increased the reward from $1,000 after another racial slur targeting black students was found Thursday scrawled on the door of a dorm room. It is at least the fifth report of a racist message in recent months.
