INITIAL ALERTEmail
An independent medical professional has found that former UNR medical student Matthew Peirce Mahaffey represents a significant risk of substantial harm to the health and safety of others. Mahaffey is prohibited and excluded from being present at any University properties or attending any University functions. If you see him on any University property or at any function, please call 911. There will be an increased police presence around UNR Med locations.
Verbatim excerpt of the email body from UNR Medical School Dean Paul Hauptman, quoted in full by This Is Reno and corroborated by KOLO-TV, Fox Reno, and 2News
The same body text was forwarded by President Brian Sandoval to all UNR students and employees later on July 12, 2024
Notably, the email provides no description of the risk type — recipients criticized the warning as 'vague,' especially given the simultaneous instruction to call 911 on sight
Context

Background

On Friday, July 12, 2024, UNR Medical School Dean Paul Hauptman sent an email to medical school students and faculty warning that former student Matthew Peirce Mahaffey posed a significant risk of substantial harm. The email was subsequently forwarded to the entire UNR community by President Brian Sandoval. Mahaffey was banned from campus and instructed that anyone seeing him should call 911. However, the email provided no details about the nature of the threat, leaving students and staff frustrated and anxious. A university spokeswoman stated they were not aware of any imminent threat and that there was no active search for Mahaffey. Public records revealed that Mahaffey, an Iraq war veteran, had pleaded guilty to voluntary manslaughter in 2011 after shooting and killing a friend in downtown Reno, citing post-traumatic stress disorder. The incident raised questions about how universities communicate threats when balancing the need for transparency with legal and privacy constraints.
