Police searched but found no threat, and at 1:23 p.m. PDT students received an AlertU message that read, \"Campus is clear and the lockdown has been lifted,\" per the [Coast Report, GWC's student newspaper](https://www.coastreportonline.com/news/article_b82b28d4-c777-11ed-bf7b-77097b28f338.html). The same Coast Report coverage tied the threat to a former student/employee who had sent violent, sexually explicit emails (containing personal information apparently scraped from LinkedIn and Facebook) to about 20 employees, some of which IT had initially deleted as spam. The case underscores how unevaluated threatening communications can escalate into a campus-wide emergency lockdown.",
