Roof Timeline — September 10, 2025
:::caution Charged, not convicted Tyler Robinson is charged, not convicted. Every entry below describes what the probable-cause affidavit, campus surveillance summaries, reported testimony or citizen frame analysis allege about the roof. No court has adjudicated any of it. :::
This is the roof-only clock. Entries are limited to things that happened on, at, or about the Losee Center roof, and they run from the morning approach through the scene processing and footage releases that came afterward. For the whole day use September 10, 2025; for the escape after the drop use Post-Shot Escape; for the version of this sequence written from the Timeline section's angle, with the feasibility disputes worked through in detail, see Roof Jumping Timeline.
All times are Mountain Daylight Time, the Utah clock.
Before — Approach and Ascent
| Time | What is alleged | Source layer |
|---|---|---|
| 11:50 AM | Figure walking in the grassy area north of Campus Drive, described as limping, heading south toward a pedestrian tunnel. | Affidavit-derived summary |
| 11:52 AM | Movement tracked through stairwells up toward the Losee Center roof, roughly 150 yards from the courtyard. | Affidavit-derived summary |
| 11:53 AM | Paused at the top of stairs, cell phone out and put back, then down into the tunnel and up a parking-garage stairwell. | Affidavit-derived summary |
| ~11:55 AM | Citizen frame analysis claims a waistband bulge on the parking-structure stairs. Contested; a bulge in a still is not a rifle. | Citizen analysis |
| 12:02 PM | Walking the north side of the Losee Center, still limping, entering through the southeast corner doors. These are the stairwell frames later released in "enhanced" form — Stairs Guy Identity Gap. | Affidavit + FBI release |
On the Roof — Railing, Assembly, Run, Position
| Time | What is alleged | Source layer |
|---|---|---|
| 12:15 PM | Crossed a railing from a public walkway onto the roof, ran across it, and moved into a shooting position. Citizen route maps stress how low and open the railing access is — a security-gap point, not an identity proof. | Affidavit-derived summary |
| ~12:15 PM | 15–20 feet past the railing, reported testimony from Officer Bagley places the recovery of a screwdriver — the point the account treats as where the rifle was assembled. See The Screwdriver and the Crime-Scene Tape. | Reported testimony |
| Not fixed | The runner enters the visible camera frame 1–3 steps past that drop point, with 10–11 running steps measured between reference marks. The released footage therefore begins after the interval that would corroborate the assembly stop. See The Tactical Roof Run. | Citizen measurement |
| 12:17 PM | Climbed over a short wall and crouched on the north side of the roof. | Affidavit-derived summary |
| 12:22 PM | Stood, ran west, scooted toward the edge — the limp no longer noticeable — and lay down facing the courtyard, roughly 430 feet from the stage. A lateral crawl into final position is described in citizen readings of the frames. | Affidavit + citizen analysis |
| 12:22 PM | Final position is described as prone behind a low roof lip, set back from the edge, which raises the sight-line question on Line of Sight Behind the Roof Lip. | Citizen objection |
The Shot and the Drop
| Time | What is alleged | Source layer |
|---|---|---|
| 12:23:00 PM | A single shot fired from the roof, per the affidavit summary. Competing public clocks include 12:23:27, 12:23:30 and 12:27 — see Shooting Time Disputes. | Affidavit |
| 12:23:30 PM | The timestamp this site uses as the moment of impact. | Site standard |
| 12:23:29–12:23:54 | Four surveillance stills are said to trace movement from the firing position to the northeast corner in about 25 seconds. This is the tightest published egress sequence and the anchor for feasibility argument on both sides. | Citizen frame analysis |
| 12:24 PM | A dark item — described as a rifle wrapped in a towel — is placed on the rooftop; the figure lowers himself onto the grass and runs north. The affidavit language is lowered himself, not jumped. See Rifle Wrapped on the Roof. | Affidavit-derived summary |
| 12:26 PM | First dispatch report of the shooting, per police audio — three minutes after the affidavit's shot time. | Dispatch audio |
After — Scene Processing and Releases
| When | What happened | Source layer |
|---|---|---|
| Sept 10, afternoon | The roof is processed: orange evidence markers and placards are placed on the gravel surface, photographed from above. | Scene photography |
| Sept 10, afternoon | A KSL news helicopter films the roof. Citizen review of that footage reports no crime-scene tape at the railing and no visible screwdriver — a discrepancy against the reported tape testimony. | Broadcast footage + citizen review |
| Sept 10, undated | Officer Bagley's body-worn camera reportedly stops recording while he is still on the roof; the reported explanation is battery. See Officer Bagley — Body Cam Died on Roof. | Reported testimony |
| Sept 11, 7:17 PM CT | A second set of stairwell photos is released publicly, described by officials as "enhanced." Commentators note the accused was reportedly already in custody by then. | FBI release |
| Undated | Per the FBI's account, Matt Robinson recognized his son from video of the figure dropping off the roof. Critics respond that the figure in the released frame is too small to identify anyone from — a dispute about image quality, not an allegation that anyone lied. | FBI account + criticism |
| July 2026 | Prosecutors reportedly play rooftop surveillance at the preliminary hearing, including a prone position and shot sequence. Observers dispute resolution and face-ID quality; summaries also disagree on whether any clip shows the shot itself. | Courtroom reporting |
| July 29, 2026 | Sam Parker publishes the annotated roof-run and screwdriver frame measurements now covered on this section's other pages. | Citizen publication |
The Gaps in This Timeline
Three intervals are missing rather than disputed. First, nothing covers the window between the railing crossing and the runner entering the camera frame — the exact interval the screwdriver account depends on. Second, no continuous clip has been released for the drop off the roof; the public record is four stills. Third, no timecoded aerial footage has been produced to place the crime-scene tape question in time. Each gap corresponds to a record that exists and has not been published — the standing subject of the Cover-Up section.
Citizen claim clusters that hang off this clock (each has its own Level 3 page): Military Lateral Crawl · Black Clothing vs Jeans · No Muzzle Flash or Recoil · Roof Figure Identity · News Helicopter · Decoy Claims · Pre-Shot Signal · Multiple Roofs.
Laws (Charlie Kirk)
The unreleased continuous UVU rooftop footage with authenticated timecodes, the roof evidence log listing what was recovered where and when, the scene-processing photographs showing marker and tape placement, and the timecoded KSL aerial footage are things the Charlie Kirk Investigation Laws may result in powerful truths coming out that aren't out yet.
Commentator coverage: Citizen journalist Ian Carroll has scrutinized this roof sequence in his own analysis — saying no rifle is visible on the released roof-figure frames, flagging a clothing mismatch with the accused, and flying his own drone over the Losee Center roof to test the published geometry.

Interesting
- Reviewers say no tape and no screwdriver appear in KSL helicopter video.
- Robinson's exact unit number was reportedly Google-searched in Hebrew months earlier.
- A Parscale FARA filing is dated exactly eight days after the killing.
