Three Blood Drops, Two Worlds

Prosecution and defense experts use three blood drops, the roof geometry, a mannequin, reconstructed snow, and competing impact trajectories to argue incompatible accounts: Samuel was struck or pushed, or he fell and hit the shed on the way down.

A simulation can fit sparse observations while remaining non-identifying: different assumptions and test setups reproduce the evidence but imply opposite underlying mechanisms.

The experts openly acknowledge uncertainty, and forensic reconstruction is not model evaluation.
