The ongoing trial concerning the tragic demise of soccer star Senzo Meyiwa witnessed a momentous turn on Monday as a DNA expert, Captain Mmampshedi Masetla, took to the stand to unveil forensic findings that brought substantial clarity to the case.
Senzo Meyiwa trial: DNA expert details forensic analysis of crime scene
The courtroom was filled with anticipation as the defence and prosecution attentively listened to Masetla, a senior forensic officer, delving into the DNA analysis process meticulously carried out in the Science Laboratory of the police department.
With a BSC degree obtained in 2000 and an honours qualification bestowed in 2001, Masetla’s expertise was a major asset to the State’s case.
Masetla embarked on explaining the essence of DNA and its significance in identifying individuals.
He highlighted that an individual inherits half of their DNA from each parent and that the forensic footprint remains identical throughout a person’s body.
His responsibility encompassed analysing DNA results, interpreting them, and carrying out forensic comparisons.
On the witness stand, he meticulously explained the preliminary testing process for blood on exhibits using specific chemicals in a dark room.
Positive results from these tests then undergo DNA extraction, using chemicals to isolate DNA from a sample, followed by a process called PCR targeting specific regions of DNA.
Each step was crucial to ensure the accuracy and reliability of the results.
What the DNA results revealed about the Meyiwa crime scene
Masetla referred to a document compiled on 4 April 2019, detailing the findings from various exhibits associated with the Meyiwa case.
The revelations were astonishing as DNA samples taken from various spots within the crime scene were scrutinised. From door handle swabs, blood swabs near the TV stand, and even beverage cans, each item held a narrative.
The DNA findings excluded many individuals from being connected to certain exhibits, yet intriguingly, linked others.
Notably, a swab from a Smirnoff can matched Zandi Khumalo, while swabs from a Heineken can and various blood swabs matched the deceased, Senzo Meyiwa.
However, all accused were excluded from all samples, including Kelly Khumalo, her mother Gladness, Longwe and Mthokozisi Twala, as well as Tumelo Madlala.
The courtroom held its breath as each DNA result was read out, each one either connecting or distancing individuals from the scene of the crime.
As the trial progresses, the anticipation for justice grows stronger, with the hope that forensic evidence provided by Masetla will be instrumental in unveiling the truth behind the tragic death of Senzo Meyiwa.
The Senzo Meyiwa trial resumes on Tuesday.
