A federal arson trial for Jonathan Rinderknecht, accused of starting the deadly Palisades Fire in Los Angeles, hears conflicting testimony from firefighters about fireworks. According to reports, firefighters disagree on details related to fireworks—information presented as part of evidence connected to how the fire began. The testimony centers on observations and interpretations made at the scene, with the conflicting accounts creating uncertainty about whether fireworks were involved and, if so, how they relate to the start of the blaze.

The trial proceeds with the prosecution presenting its case that Rinderknecht intentionally set the fire, while the defense challenges elements of the evidence and the reliability of witness accounts. The reports indicate that the courtroom dispute over the fireworks-related testimony is one of the points raising questions for the jury or judge regarding the circumstances of ignition. The proceedings continue as additional evidence and witness testimony are presented.
