(AP) - Authorities late Thursday arrested thesuspect in the slaying of a Wesleyan University student who policesaid had threatened to kill other students and Jews.

A police spokesman said 29-year-old Stephen P. Morgan was takeninto custody in the central Connecticut town of Meriden, about 10miles from Middletown, and turned over to police investigatingWednesday's fatal shooting of 21-year-old Johanna Justin-Jinich.

Middletown police said they planned to make an announcement lateThursday night.

Justin-Jinich was shot several times inside a bookstore cafejust off campus by a gunman wearing a wig.

An official with knowledge of the investigation told The AP thatpolice stopped Morgan shortly after the shooting, spoke to him andlet him go, only to later realize he was a suspect.

When police confiscated Morgan's car they found a journal inwhich he spelled out a plan to rape and kill Justin-Jinich beforegoing on a campus shooting spree, said the official, who spoke onthe condition of anominity because the case is under investigation.

Justin-Jinich, of Timnath, Colo., came from a Jewish family, andher grandmother was a Holocaust survivor.

Morgan's brother told the AP that Morgan wasn't anti-Semitic.His family issued a statement pleading with Morgan to turn himselfin "to avoid any further bloodshed."
