Except he wasn't a member of the MIT community. He was a Fellow at Harvard University Edmond J. Safra Center for Ethics, but not a student or faculty member at MIT.
However, as the report notes, Swartz had connections to the Institute: "He was a regular visitor to the MIT campus and interacted with MIT people and groups both on campus and off. … He was a member of MIT's Free Culture Group, a regular visitor at MIT's Student Information Processing Board (SIPB), and an active participant in the annual MIT International Puzzle Mystery Hunt Competition. Aaron Swartz's father, Robert Swartz, was (and is) a consultant at the MIT Media Lab. Aaron frequently visited his father there, and his two younger brothers had been Media Lab interns."
