  "context": "[Coker University](https://en.wikipedia.org/wiki/Coker_University) is a small private bachelor's institution in Hartsville, South Carolina, with about 1,100 students and a compact 50-acre main campus. On the morning of March 28, 2023, a [suspicious package was discovered near the campus entrance at 4th Street and College Avenue](https://www.wbtw.com/news/pee-dee/hartsville/suspicious-package-prompts-shelter-in-place-order-at-coker-university-in-hartsville/) at approximately 9:30 a.m. EDT. Coker triggered a [Cobra Alert ordering shelter-in-place](https://wpde.com/news/local/coker-university-hartsville-south-carolina-on-lockdown-as-police-investigate-suspicious-package-cobra-alert), which Hartsville Police escalated by requesting the [South Carolina Law Enforcement Division (SLED) bomb squad](https://www.wmbfnews.com/2023/03/28/coker-university-placed-lockdown-after-suspicious-package-delivered/). SLED responded, evaluated the package, and cleared it as non-hazardous. The shelter-in-place was lifted at 11:11 a.m. EDT. The case is significant because it demonstrates how small liberal arts colleges rely on state-level resources (SLED in South Carolina, equivalent agencies elsewhere) for specialized threat assessment. The 'Cobra Alert' branding (drawn from Coker's athletic identity) reflects a broader trend of small institutions personalizing emergency notification systems to encourage opt-in subscription.",
  "keyFindings": [
    "Coker's Cobra Alert system uses the 'COBRA ALERT:' header as its signature emergency-message marker, paralleling alert-naming conventions like UF's 'UF Alert' or UNC's 'Alert Carolina'",
    "The response relied on the state-level SLED bomb squad, illustrating small-campus dependency on state resources for bomb response",
    "The initial alert did not name the threat type, saying only 'Emergency at 4th Street and College Avenue'",
    "The package was located at the main pedestrian entrance to campus; the university directed shelter-in-place rather than evacuation"
