CHICAGO (CBS) — A University of Chicago graduate student was found hanged Sunday in the geophysical science lab building where he worked.

John Adams, 26, was found hanged inside the Henry Hinds Laboratory for Geophysical Sciences, at 5734 S. Ellis Ave., according to the Cook County Medical Examiner’s office.

Adams, of the Hyde Park neighborhood, was dead on the scene at 7:52 p.m. Sunday, according to the medical examiner’s office.

A source said he was a graduate student worked in the building, which is listed as the Jones Laboratory of the Division of Physical Sciences.

A Monday autopsy confirmed Adams died from hanging and the death was ruled a suicide, the medical examiner’s office said.

The building where Adams died houses the Geophysical Sciences Department, which was formed in 1961 by combining the Geology and Meteorology departments.

It was not specified whether Adams’ body was found in a lab, a classroom or another part of the building.

The University of Chicago Police incident report only indicated that a “deceased person” was discovered Sunday evening, and indicated that he had died sometime between 4 p.m. Friday and 7:30 p.m. Sunday.
