Hinrichs
In a press conference the next day, OU president David Boren identified Hinrichs, a 21-year-old mechanical engineering student, as responsible for the detonation. Originally from Colorado Springs, Colorado, Hinrichs was a National Merit Scholar who graduated from Wasson High School in May 2002. His father, Joel Hinrichs Jr., described him as a "very private individual" who had gone through "several severe bouts of depression". Hinrichs' depression was noted as early as ten years old. His father believes that the "underlying cause was his inability to bond with other people. He couldn't make friendships," and also said that Hinrichs began counseling at the university's on-campus health center two years earlier. He did not know if his son was still seeing a counselor, and denied knowledge of the young man's suicidal ideations.
Hinrichs was a member of Triangle Fraternity, a social fraternity of engineering, science and architectural majors. Hinrichs' father said that his son had "recently moved out of the Triangle fraternity house because "he didn't bond, didn't relate well to the other fraternity members." In the chapter meeting following the bombing the members of his fraternity were asked to direct all questions and comments to one member of their fraternity and not to discuss anything with the media, this was advised in hopes of limiting rumors and other theories.
