A Connecticut detective who investigated the 2009 killing of a Wesleyan University student says the defendant searched the Internet the night before for information about the Columbine High School and Virginia Tech mass shootings.

The detective's testimony Tuesday came on the fourth day of Stephen Morgan's trial before a panel of three state judges. The 32-year-old native of Marblehead, Mass., is charged with murdering 21-year-old Johanna Justin-Jinich of Timnath, Colo., at an off-campus bookstore cafe. His lawyers are pursuing an insanity defense.

State police Detective Brian Ferrucci examined Morgan's computer and the Internet searches he performed before the killing. Ferrucci also said Morgan looked at anti-Semitic websites.

The prosecution rested its case and the defense began calling its witnesses Tuesday.

The trial resumes Wednesday.
