The Yale Police Department has posted an officer outside the Joseph Slifka Center for Jewish Life in response to the slaying of a Jewish student at Wesleyan University on Wednesday.

The suspect in that killing, 29-year-old Stephen Morgan, who has yet to be apprehended, “expressed threats in his personal journals toward Wesleyan and/or its Jewish students,” as the university put it in a statement on its Web site.  Wesleyan remained under lockdown until Thursday evening as a result of the threats, and the authorities asked a synagogue in Middletown, Conn., to close its doors temporarily.

“There will be an officer on Wall Street until the alleged perpetrator is captured,” Lina Zerbarini, Slifka’s director of operations and associate rabbi, wrote to students shortly after 8 p.m. Thursday. “If you see anything suspicious, call Yale Police at 2-4400.  Of course, if you sense any immediate threat, call 911.”
