Disputed Details

Conflicting or time-sensitive information

Several differences in the sources are timeline updates or legal wording differences rather than simple contradictions.

Time-based update
Initial deaths versus final fatality count

Early coverage reported three deaths and two people critically injured. Later reporting and court records state five deaths.

1 November reports

EL PAÍS and Reuters reported three deaths and two critical injuries.

Later reports / courts

EL PAÍS later reported the fifth death, and court material refers to five deaths.

This reflects the later deaths of critically injured attendees, not an error in the early known count.

Cause framing
Immediate trigger versus underlying causes

Early reports discussed a flare or firecracker and panic. Later judicial findings focused on crowd-management failures.

Early media framing

Some reporting described a flare/firecracker and subsequent rush or panic as the immediate trigger.

Judicial framing

The Provincial Court release emphasised overcrowding, blocked routes and routing arrivals onto a saturated floor.

Both can be true at different levels: immediate trigger versus conditions that made the crush deadly.

Legal count wording
Injury counts in court material

Court press releases use different injury formulations.

2016 Provincial Court

Referenced five deaths and 29 injuries.

2018 Supreme Court

Referenced five deaths and 14 injury counts in the confirmed ruling summary.

This is treated as a legal/procedural wording difference, not a settled single medical total.

Not Verified

Details not confirmed

These details were not confirmed from the reviewed source set.

Trigger identity
The identity of the person who allegedly set off the flare/firecracker was not verified.
Original social post
A direct original Steve Aoki social media post was not verified; only secondary reproductions were found.
2012 address wording
The current official venue address was verified, but not the exact official address wording used in 2012.
Municipal report URL
A directly accessible official municipal investigation report URL was not verified in the source set.
