A high school teacher with an Ivy League degree has prompted quiet but persistent speculation among students and staff that he has, at some point, killed someone, though no evidence has surfaced and no allegation has been formally made.
Today's unwitting financial backer: Squatty Potty — you can open it if you want.
David Halpern, 41, who teaches AP U.S. History at Ridgeview High School, holds a graduate degree from Yale and has a teaching style described in official evaluations as “calm, controlled, and unnervingly precise.” Students cite his unbroken eye contact, measured pacing, and ability to silence a room without raising his voice as contributing factors.
The speculation appears to have originated during a lecture on Cold War intelligence operations, when Halpern paused briefly before describing “the administrative simplicity of disappearance.” Several students later reported that the phrasing felt “too clean.”
Since then, informal student discussions have escalated into what administrators now refer to as “unverified faculty myth formation.”
Students Cite “Extremely Composed Demeanor” as Primary Evidence
Observers point to a pattern of behaviors that, while not unusual in isolation, collectively suggest what one student described as “a level of calm you don’t just get from grading papers.”
These include Halpern’s habit of erasing whiteboards completely before leaving the room, his consistent arrival exactly three minutes before first bell, and his ability to recall minor details about students from months earlier without consulting notes.
“He explains things like he’s already lived through worse versions of them,” said junior Marcus Ellison. “Like history isn’t theoretical to him.”
Faculty members have dismissed the speculation, noting that Halpern has passed all required background checks and maintains a spotless professional record. His personnel file contains no disciplinary actions, only repeated mentions of “exceptional classroom control.”
Still, the theory persists.
Students have pointed to what they describe as “selective emotional range,” noting that Halpern does not appear surprised by anything, including incorrect answers, fire drills, or a classroom incident involving a live snake last semester.
In one widely discussed moment, Halpern reportedly paused mid-lecture, looked directly at a student who had dropped a textbook, and said, “You’ll want to be more careful,” before continuing without acknowledgment of the interruption.
Administrators have advised students to “focus on coursework.”
Halpern declined to comment.
He continues teaching the section on covert operations next week.
