How a police call-out solved the ‘puzzle’ behind the stabbing death of a of a lovable personal trainer – as a man and woman are arrested

  • A 40-year-old woman and 42-year-old man had been taken into custody
  • The pair were each charged with a count of murder in the death of Mark Carson
  • It’s alleged a violent altercation between the pair and Carson ended his life 
  • The personal trainer was found dead at his Pacific Haven, Qld, home on April 3 

A call for information from the public helped police solve a ‘puzzle’ when two people were arrested this morning and charged with one count each of murder in the violent death of a personal trainer. 

The arrests follow an investigation in which the man, 42, and woman, 40, had spoken to police a number of times and offered assistance ‘to a point’ in relation to the death of Mark Carson on April 3.

Queensland Police had last week made a renewed call for any information about the death of Mr Carson, 58, leading to the execution of a search warrant at a Maryborough residence.

Police allege the pair were involved in an altercation with Mr Carson, a personal trainer and volunteer firefighter, during which he sustained fatal injuries.

In the early days of the investigation, police said Mr Carson died from a severe wound he suffered in a physical fight with the pair at his Pacific Haven residence, near Hervey Bay.  

‘We hope today’s arrests bring some closure to Mark Carson’s family,’ Detective Senior Sergeant David Harbison, Officer-in-Charge of the Maryborough CIB, said. He acknowledged that critical information provided by the local community had helped bring about the arrests.

Detectives had previously described the investigation into Mr Carson’s death as a ‘puzzle’. 

Officers found his body after the 42-year-old man called triple zero at 12:08pm on Saturday, April 3. 

Police believe Mr Carson might have died hours before that call was made, having established that the couple arrived at the home about 8am. 

Detectives had earlier called for information from anyone who saw the couple’s light blue four-door 2011 Hyundai Accent sedan near Mr Carson’s home between 8am and about midday. 

Police earlier released a CCTV photo of the couple's light blue four-door 2011 Hyundai Accent sedan near Mr Carson's home in the quest for more information
