Murdaugh Defense Challenges Murder Timeline with Expert Testimony Ahead of Retrial Hearing

Alex Murdaugh is heading toward a second murder trial, and his defense team is already targeting a key weakness: the time of death. Defense attorney Dick Harpootlian has signaled that the official timeline of the June 2021 killings at the Murdaugh family's Moselle property could be a major issue — and possibly create reasonable doubt, according to ABC News 4.
Murdaugh was convicted in 2023 of killing his wife Maggie and son Paul. A retrial hearing is set for August 14th, when Judge Debra McCaslin will rule on where the new South Carolina trial will be held and decide on pending motions, according to KUTV.
The prosecution's case against Murdaugh relied heavily on a tight timeline. Investigators placed the murders at around 8:49 p.m. on June 7, 2021 — largely based on a video found on Paul's phone showing all three family members alive at the dog kennels. But Harpootlian has said that timeline could be completely wrong, according to WACH.
If the time of death is off by even an hour, it could give Murdaugh an alibi. That is why the defense is expected to challenge how investigators determined when Maggie and Paul died. In a murder trial, that kind of doubt can be powerful.
Death investigator Joseph Scott Morgan — who helped write the national standards for determining time of death — broke down the science in an episode of the podcast Criminally Obsessed. Coroners and medical examiners use several physical clues, according to Newschannel 9. These include body temperature, rigor mortis (when muscles stiffen), and livor mortis (when blood pools and skin discolors after death).
Each method gives a window — not an exact minute. Heat, humidity, and the location of a body can all shift those estimates. At an outdoor scene like Moselle in a South Carolina summer, those variables matter a lot. Morgan reviewed the coroner's actions in this case and raised questions about how the timeline was established, according to KTUL.
Morgan pointed out specific concerns about the way time of death was handled at the Moselle crime scene. Proper death investigation requires documenting body temperature at the scene and carefully tracking environmental conditions. Any gaps in that process can weaken the reliability of the official timeline, according to Fox17.
Morgan's expert view is that if the coroner did not follow standard protocol precisely, the defense could argue the estimated time of death is unreliable. That would open the door to challenging the prosecution's entire sequence of events on the night of June 7, 2021, according to Idaho News.
The August 14th hearing is a critical step before any new trial begins. Judge McCaslin will decide where the case will be tried — a venue change is possible given the massive media attention the first trial received. She will also rule on several pending legal motions, according to My News 4.
The defense's strategy is becoming clearer: attack the forensic evidence and cast doubt on what investigators said happened and when. With time of death science being imprecise by nature, Harpootlian appears to be betting that a jury in a second trial could see the timeline very differently, according to WGXA.
