On Friday, November 1, 2024, University of Dayton Public Safety received a bomb threat from a resident of Caldwell Apartments, a UD-owned apartment building near the Cronin Athletic Center on the Marianist Catholic university's residential south campus. UD Public Safety and the Dayton Police Department deployed an explosive-detection dog and searched the building, finding nothing of concern. In an unusual choice, UD declined to evacuate the building, instead increasing patrols throughout the day while residents stayed in place.

UD Alert: The Department of Public Safety has received a bomb threat reported by a resident of Caldwell Apartments.

Continue normal activity and avoid the immediate vicinity of Caldwell.

Reconstructed from Flyer News's specific description of UD's communication and the choice not to require evacuation
Notably, UD did not evacuate Caldwell — a decision that contrasts with peer institutions like Holy Cross (which evacuated its Mount St. James campus over a January 2024 threat) and reflects UD's judgment that the threat was low-credibility
The Caldwell Apartments are UD-owned student housing near the Cronin Athletic Center on the south side of UD's residential campus footprint

Reconstructed from the Flyer News all-clear quote: 'After searching Caldwell apartments, they found nothing of concern'
UD's choice to continue heightened patrols even after the all-clear is a hallmark of risk-managed response — visibility without escalation
No suspect was publicly identified; the lack of arrest or public update suggests either an internal resident incident or unverifiable phoned-in threat
Context

Background

On Friday, November 1, 2024, a resident of Caldwell Apartments — a University of Dayton student housing building near the Cronin Athletic Center on UD's residential south campus — reported receiving a bomb threat. UD Public Safety and the Dayton Police Department opened an investigation, deploying an explosive-detection K-9 to sweep the building. In an unusual decision for a Catholic university bomb-threat response, UD did not evacuate Caldwell residents — instead asking them to continue normal activity while officers conducted the sweep. The K-9 found nothing; the all-clear was issued the same day. UD, founded by the Society of Mary (Marianists) in 1850, is one of the largest Catholic universities in the Midwest, with about 11,000 students. The Caldwell threat was one of a string of incidents reported across the UD student neighborhood during fall 2024, including unrelated shootings on Evanston Avenue, and contributed to the November 1, 2025 campus shooting the following year that injured a UD student.
Analysis

Key Findings

UD's decision not to evacuate Caldwell Apartments during the bomb-threat sweep — relying instead on K-9 search and increased patrols — was atypical compared to peer Catholic institutions that evacuated under similar threats
The K-9-led sweep produced no evidence, and no suspect was publicly identified, indicating the threat was either internal to the resident community or a phoned-in hoax
The Caldwell incident was one of several disruptions in UD's residential student neighborhood during fall 2024, foreshadowing the November 2025 on-campus shooting
Outcome
UD Public Safety and the Dayton Police Department, assisted by an explosive-detection K-9, swept Caldwell Apartments and found nothing. UD police continued patrolling the building throughout the day. Residents were not required to evacuate or take any additional action. No suspect was publicly identified. The threat fit a pattern of unfounded bomb threats reported at UD residential properties during the fall 2024 semester.
