Ok, wait, no jokes: Wesleyan University is in lockdown as cops conduct a manhunt for a killer who shot his ex, a student, at a campus bookstore.

The shooter is Stephen Morgan, 29, and now cops say he might be targeting Jews.

He is a creepy fucker, this Stephen Morgan, as is apparent in the surveillance pic released from Broad Street Books, where he killed Johanna Justin-Jinich. And he ruined the Spring Fling.

Cops recovered his gun and his wig, and he might be in New York or Massachusetts.
