About

Paul McManigal first testified about his handling of digital evidence. He received an unprocessed extraction attributed to Alex Murdaugh's phone and created a reduced copy based on attorney-directed redaction decisions, without performing additional analysis. He said the call logs were not redacted.

McManigal also authenticated custody records for an iPhone attributed to Paul Murdaugh. He said he could not unlock the phone or otherwise alter its data. On cross-examination, he testified that it was powered off when he received it and that he later charged it, but he could not recall whether its battery had been fully drained on arrival.

Later, McManigal explained the accelerometer-driven Raise to Wake feature and described movement and throw tests using the same iPhone model as Maggie Murdaugh's phone, with a slightly newer operating-system version. Gentle movement tended to illuminate the display, while nine of ten frisbee-like throws left it off. He offered the testing only to show that throwing a matching-model phone would not necessarily activate its screen.

Cross-examination established that McManigal conducted the experiments alone without recordings, measurements, documented controls, or the test phone in court. He acknowledged that he was not an engineer, did not know the activation threshold, and could say only that the screen might remain off in the proposed scenario. On redirect, he distinguished a gentle pickup demonstration from his more aggressive throws. On recross, he agreed that reliable results would require more than ten trials and that he had not applied the statistical method he described.

20232023 Murder TrialJan 23, 2023 โ€“ Mar 3, 2023Called by prosecution

Paul McManigal handled phone extractions and custody evidence, then testified as a cell-phone-forensics expert about Raise to Wake testing with a matching-model phone. Cross-examination limited the significance of his undocumented, variable experiment to the possibility that a thrown phone's screen might remain off.

Summary

Paul McManigal explained the limited redaction of an extraction attributed to Alex Murdaugh's phone, confirmed that call logs remained intact, and documented his unsuccessful attempt to unlock the phone he believed was Paul's.

Summary

Paul McManigal testified that a thrown iPhone may not activate Raise to Wake, while acknowledging different software and variable test results.

Quoteโ€œNo, not at all. Sometimes the screen would turn on when I threw, land face up, and then the screen would turn on. But a lot of times I would throw it and the screen would not turn on. It depends on how that accelerometer registered that movement.โ€— Paul McManigalMcManigal acknowledged that the experiments did not produce uniform results and tied the variation to how the accelerometer registered movement.Open in transcript →Watch this moment ▶
Quoteโ€œIf the phone is thrown, the screen does not always turn on. In my experimentation, I determined that when the phone is thrown more like a frisbee, nine out of ten times the screen does not turn on. The times that it did turn on most often was when I pick it up and tried to shake it, then the screen would come on briefly.โ€— Paul McManigalThis was McManigal's principal conclusion from testing whether a thrown phone would necessarily activate its screen.Open in transcript →Watch this moment ▶

Summary

The defense exposed documentation and expertise limits in McManigal's Raise to Wake experiments, but the judge declined to strike his qualified opinion that a moved phone's screen might remain off.

Quoteโ€œIt did not cross my mind to video record my experiments. I just did the experiments to determine whether or not the screen would turn on.โ€— Paul McManigalMcManigal explained why the experiments supporting his rebuttal opinion had not been video recorded.Open in transcript →Watch this moment ▶

Summary

Paul McManigal acknowledged that he did not apply the statistical control-and-sample method he described when judging his experiment's reliability.
