Police said Tuesday that they believe the man found dead near Yale-New Haven Hospital on Monday morning has committed suicide. Initial reports indicate that the man jumped from the fourth floor of a parking garage in the area of 2 Howe St., but the investigation is still open, said New Haven Police spokesman Joe Avery. A nurse found the body Monday morning and called police, but city officials appeared unaware of the discovery when contacted later that day. Officials have yet to release any statement on the death. —Colin Ross
