Officials at the University of Wisconsin-Madison say they defused threats from 125 troubled students, employees and area residents under a little-known program launched two years ago in response to deadly tragedies on college campuses in Virginia and Illinois.

But the program didn’t identify at least three individuals before they caused problems at Wisconsin’s flagship campus, including threats against a campus leader, a bomb threat and a murder near campus.
