In 2023, a South Carolina jury convicted Alex Murdaugh of shooting his wife Maggie and their 22-year-old son Paul at the family's Lowcountry hunting estate. Prosecutors argued he killed them to cover up a financial-crimes scandal. He got life in prison. The state Supreme Court unanimously overturned that conviction in May 2026 — the trial clerk had made improper comments to jurors, including telling them to "watch his body language." A retrial is now scheduled for April 2027. Murdaugh stays in prison regardless — he is serving a 27-year state sentence and a concurrent 40-year federal sentence for financial fraud. Since then, his defense team found something the first trial never fully examined: unknown male DNA under Maggie's fingernails, with no match to Alex Murdaugh or anyone in his family. The defense has been fighting to test it independently. A judge rules on August 14.

1. Murdaugh's Team: The State Found Unknown DNA and Never Ran It Down (defense attorneys)

Unknown male DNA is under the murder victim's fingernails — and the state never identified whose it is.

Murdaugh's attorneys want to independently test the DNA. They filed a motion on July 30 for forensic genealogy testing via Othram Inc., which applies single nucleotide polymorphism (SNP) analysis to build investigative leads from partial or degraded samples. Unlike standard STR testing — which the defense says "performs poorly on degraded, low-quality, or mixed samples" — SNP analysis can map distant relatives from a fragmentary profile. That mapping could produce a name or a family tree.

The state never properly investigated this DNA, the defense argues. On August 5, Murdaugh's team filed a supplemental motion demanding that prosecutors hand over all exculpatory material gathered since the original trial — updated disciplinary records on witnesses, any witness deals, and forensic findings. Their argument is direct: if the state's case is as airtight as it claims, full disclosure costs the prosecution nothing.

2. Prosecutors: The DNA Is Contamination and the Evidence Still Points to Alex (SC Attorney General Alan Wilson, state prosecutors)

Maggie had her nails professionally done the day she was killed. Touch DNA proves nothing about who murdered her.

Prosecutors call the DNA "a very partial and incomplete profile." Maggie Murdaugh had a professional manicure on June 7, 2021 — the day she was murdered. Touch DNA accumulates from any surface contact: a nail salon, a door, a handshake. Prosecutors say the fragmentary profile is consistent with routine contamination, not with contact from an attacker.

They also point to what's absent from the murder scene. Maggie's body showed no defensive wounds and no signs of a physical struggle with an unknown person. Prosecutors called the proposed Othram testing an "unnecessary boondoggle" and told the defense to specify its protocols before any independent analysis could proceed. South Carolina Attorney General Alan Wilson said in May 2026 he would "aggressively seek to retry" Murdaugh, and his office's position is that the underlying murder evidence — motive, opportunity, Murdaugh's own statements — is the same as it was in 2023.

Where This Lands

Judge McCaslin rules August 14 on whether the defense gets to run its own DNA test. If she approves it, Othram's genealogy analysis could generate a list of people related to whoever left that trace — a possible alternative suspect, or a dead end that ends up hurting the defense. If she denies it, the defense heads to trial in April 2027 without one of its most concrete new pieces of physical evidence.

What both sides agree on: the second trial will not look like the first. The clerk who poisoned the jury pleaded guilty to four charges — two counts of misconduct in office, obstruction of justice, and perjury — and walked away with probation and no prison time. The Supreme Court ruled prosecutors overloaded the first trial with financial testimony. The Murdaugh family ran Lowcountry prosecution for 86 years. The defense heads to trial carrying a documented record of institutional failure — and demanding the state independently test DNA the prosecution calls meaningless.
