Briscoe and Curtis investigate the murder of Sarah Kincaid, a mathematics graduate student who was found murdered in the university library. The autopsy reveals that Sarah was strangled and also that she was 9 weeks pregnant, even though her bereaved father says she didn't have a boyfriend. Their initial inquiries are directed to a recently released ex-con but they learn that the victim had had a rather loud argument with her academic advisor, Dr. Clemente. When he is cleared however, the DNA testing of the fetus leads them to Dennis Michaels, who is engaged to Sarah's roommate. Another library patron puts them in the direction of a young preppy he saw there and it leads them to Peter Kelly, one of Dennis' good friends.
Did You Know?
Hudson University (aka Columbia University) almost certainly would have a CCTV system covering their library's interior and exterior. That they didn't have multiple views of the suspects both entering as well as leaving the library is improbable and it would have solved the case. See more
