Wesleyan University remained all but shut down this morning as the Connecticut campus urged students to remain in their dormitories, and faculty and staff members not to come to work, a day after a student was shot to death in an off-campus bookstore. The university’s Web site said the gunman, who is still at large, had no connection to Wesleyan but had written threats in his journals about “Wesleyan and/or its Jewish students,” according to the local police.

The murdered student, Johanna Justin-Jinich, a junior, apparently came to know her killer during a short summer program at New York University two years ago, according to The Hartford Courant. Near the end of the program, Ms. Justin-Jinich filed a harassment complaint about the man, Stephen Morgan. After an initial inquiry into the matter, Ms. Justin-Jinich decided not to pursue her complaint, an NYU spokesman told the Courant.

The Associated Press reported that Mr. Morgan, who is 29 years old, was the subject of a nationwide manhunt. The Wesleyan Web site said the campus would receive increased patrols by campus and local police officers. —Andrew Mytelka
