- Students who write or discuss planned attacks. Some attackers "leak" information about their plans beforehand in the form of overheard conversations, comments on social media postings, or a class journal, blog, webpage, or e-portfolio. Teachers and other school staff are in a unique position to "overhear" students who may be planning an attack. Particular urgency is needed when a student mentions a person, location, or time of an attack.
- Students with difficult school conflicts or who are dismissed or expelled. These times of separation from the resources and structure of the school environment can be a catalyst for a desperate student who sees no other way out but to kill or otherwise take revenge on those they deem responsible.
- Students with unrequited romantic relationships. While it is common for many students to experience emotional turmoil after a break-up, the resulting tunnel vision, passion, and hopelessness can drive some towards extreme action. These situations can trigger explosive bursts of anger or methodical and carefully detailed plots of revenge.
- Individuals who write manifestos or large societal messages that indicate a deeper, entrenched worldview or call to action. Many of those who plan violence do so under the rationalization of some greater cause or message they are trying to communicate. Their attacks are in some way designed to release their larger message or call others to action for their hardened point of view.
- Those who feel hopeless or are irrational in their logic. Many of those lost down the path toward violence fall out of connection with others who have the potential to refute their pessimistic logic and offer alternative views of the world outside of violence. Identify students who are isolated and out of meaningful contact with others, as well as those who are marginalized and discriminated against.
- Students who bully or are bullied. Attend specifically to bullying behavior that creates an environment in which an affected student may seethe and grow more dangerous in his or her thinking. While all those who are bullied (or who bully) are not destined to become the next school shooter, some who are bullied carry these scars and wounds with them and eventually seek revenge.
- Students who need mental health services but are not receiving help. While those with mental illness are not more likely to commit violence—in fact, people with mental illness are more likely to be the victim of a violent crime (Desmarais et al., 2014; Van Brunt & Pescara-Kovach, in press)—proper treatment can help reduce the potential for violence. This involves timely access to the appropriate care and sustained treatment to have an ongoing positive impact.
- Sociopaths and psychopaths. Although such students are rare, be concerned about individuals who take pleasure in harming others and expressing obsession-filled hate and threats of violence toward individuals or groups.
- Individuals who drop hints or threats of violence. Those who engage in violence rarely just snap; violence is often the end product of months (if not years) of planning.
- Suicidal individuals. Suicidal students may express hopelessness and desperation to escape pain, and these same feelings are often also present in many individuals who engage in extreme violence. While all suicidal people do not kill others when they attempt to kill themselves, most who engage in extreme violence end up taking their own life in the process. Many attackers feel isolated and have distorted thinking about escaping pain and, perhaps, a romanticized idea of escape from this world.
