Untested DNA Upends Murdaugh Retrial

A high-profile murder retrial now hinges on untested DNA, a missing rifle, and whether the state must open its files wider.

Story Highlights

The defense asked to test male DNA linked to Maggie Murdaugh’s nails and phone.
Prosecutors warned new DNA tests could consume what is left of key samples.
Fights over cellphone data, 3D scene scans, and ballistics dominated the hearing.
The unrecovered.300 Blackout rifle keeps weapon identity in dispute.

Defense Targets Untested DNA And Scene Evidence

Defense lawyers told a South Carolina court they want testing on male DNA tied to Maggie Murdaugh’s fingernail clippings and cellphone. They also asked for untested crime scene swabs, hair from Maggie’s hands, and a footwear impression from the feed room. They said new analysis could point to another person and test the state’s timeline. Court filings from September 18 outlined these requests, which were aimed at getting raw data to independent experts before the retrial in April 2027.

Prosecutors pushed back on the DNA plan. They warned the proposed testing could use up the small amount left from the fingernails. They asked the defense to spell out methods, goals, and likely results before any destructive step. They also said the defense already had the DNA reports before the first trial. The state argued it would share some technical files but would not agree to broad, open-ended testing that risks evidence integrity.

Missing Rifle And Ballistics Requests Drive Tension

The rifle that allegedly killed Maggie, a.300 Blackout, has never been found. The defense asked for ballistics and related records from shootings in eight nearby counties involving the same type of gun. They said those files could reveal links that matter if the murder weapon is missing. Prosecutors opposed that effort, saying that a shared caliber and area do not prove any tie to this case. The dispute over scope and relevance remains live.

Ballistics debates fit a common courtroom pattern. When a weapon is missing, lawyers turn to casings, bullets, and lab comparisons. Courts often require a clear reason to believe comparisons will help the jury. Judges do not allow fishing trips through unrelated cases. Here, the defense wants a wide review to find possible matches, while the state sees weak connections. That clash will shape how far the court lets the search go.

Phones, 3D Scans, And The Clock

The defense asked for complete cellphone extractions, location data, and scene measurements made by three-dimensional scans. They said their experts need the native files to check movement and timing at the kennels. Prosecutors said they already handed over phone records in the first trial but agreed to provide raw phone data and the three-dimensional kennel scans now requested. The defense says time is short to study complex files before trial.

"Quit telling me about stuff that y'all did to each other during the first trial. I don't care!"

Judges often face late fights like this in serious cases. The questions are simple on paper and hard in practice. What testing could really change the verdict? How much access is fair, and how fast can both sides work? Here, the court must weigh one risk against another. Withholding testing can leave gaps. Destructive testing can erase the chance for future review. The choice will set the guardrails for this retrial’s core evidence.

Why This Matters Beyond One Case

This hearing taps a wider worry many Americans share. People see a justice system that is slow to share data, quick to guard turf, and hard to trust. Defense teams say they need full access to check the state’s story. Prosecutors say they must protect evidence and avoid wild goose chases. When the government controls the files, the balance of power is uneven. Clear rules, full logs, and timely sharing can help rebuild trust on both sides of the aisle.
