about any request for leave. he did request a lighter load and i can tell you he was assigned to teach two classes online this semester. >> so when you think now in connection to these two professors who were friends, do you know about any of their personal history off dsu's campus, why would they be connected, why shannon lamb would show up in ethan schmidt's history classroom? >> we really have no idea and we have discovered at least from what i've heard no animus between the two. which doesn't make sense. the dots don't connect. there's suspicion that the suspect here was troubled at the end of his life. we don't know of any incidents. in fact, they were colleagues, they were in the same division of academic campus and they apparently socialized on occasion. we have heard nothing to support any difficulties or problems between the two. >> does this give you any pause for concern about campus safety?
