Digital Forensics: How Cellphone Evidence Convicted Alex Murdaugh

The Alex Murdaugh Case

• 👨‍⚖️ Alex Murdaugh, from an old money family of prosecutors, was convicted of murdering his wife, Maggie, and son, Paul, in 2021.
• 💸 Prior to the murder conviction, Murdaugh was disbarred and charged with stealing approximately $8.5 million from clients and associates.

Digital Forensics as the Smoking Gun

• 📱 A key piece of evidence was a video from Paul Murdaugh's phone showing the family near the dog kennels shortly before their deaths.
• 🚶‍♀️ Metadata from Maggie Murdaugh's cell phone indicated her phone was moving after she was deceased, suggesting someone physically moved it.
• 📊 While automated software can review phone data, a manual review of the database provides deeper insights, including phone unlock methods and screen activity.

Analyzing Cellphone Data

• 📍 The database can reveal details like when a phone was last unlocked, screen brightness, and 'raise to awake' settings.
• 👟 Investigators used step count data from phones to estimate movement distances and timelines, helping to place phones in specific hands.
• ⚠️ While step counts can have inaccuracies, the estimated distance derived from GPS data is considered more reliable.

Murdaugh's Phone Activity

• 📈 Alex Murdaugh's phone data showed significant movement with large step counts recorded at frequent intervals, contradicting his claim of taking a nap.
• ⏳ Investigators were able to retrieve crucial data from Maggie's phone because it was seized within 30 days, before the database rolled over.

Verdict and Sentencing

• ⚖️ Alex Murdaugh was found guilty of murder after only three hours of deliberation and received two consecutive life sentences without parole.
