DNA Expert Links Tyler Robinson to Murder Weapon at One in Trillion Probability

What was said

"For this exhibit, the DNA profile was at least 1 trillion times more likely if it originated from Tyler Robinson as the major component and 3 unknown unrelated individuals than if it originated from 4 unrelated individuals. It's possible it could be a much higher number than 1 trillion. The probability of an unrelated individual in the population who has not contributed DNA to the sample yielding this level of support is less than one in a trillion."

In an unexpected turn, the defense's own DNA expert witness from the ATF testified that forensic evidence linked Tyler Robinson to the crime at a probability capped at one trillion to one, though the actual probability could be significantly higher. The defense attorney's repeated failed attempts to discredit this testimony through inadmissible questioning were sustained by the judge, demonstrating the overwhelming nature of the physical evidence.
