Kyla Dooley, runner-up in this year’s Three-minute thesis competition, wants to pursue a career working alongside police enforcement, using her knowledge of forensics to solve criminal cases and convict perpetrators.

When rapes and sexual assaults are committed, DNA evidence can play a large role in convicting the offenders. DNA evidence collected from sexual crimes can, according to Kyla Dooley, often be tricky to analyse.

Kyla has just completed her master’s degree, specialising in Forensic Genetics, at the University of the Free State (UFS). She not only thrives in this field – graduating at the top of the Faculty of Natural and Agricultural Sciences in 2018 when she was awarded the Dean’s Medal – but her work also brought her the runner-up position in this year’s Three-minute thesis competition. 

She talked about her research on the use of male-specific DNA in the analysis of DNA evidence collected after crimes of a sexual nature have been committed.

Explaining her research, Kyla elaborates: “In most cases, the victim is female, while the offender is male. Therefore, the evidence is often a mixture of male and female DNA and this can make it difficult to analyse the male DNA and match it to a male suspect.”

She believes the solution to this is to target male-specific DNA in analysis. “This eliminates all female DNA and simplifies the process,” says Kyla.

“Unfortunately, male-specific DNA technology is not currently used in South Africa, because the DNA regions tested to date haven’t shown much success in distinguishing between males in our population,” Kyla points out.

“The goal is now to use DNA evidence, to match it to a suspect, and have the confidence that it came from him and only him. Or else defence lawyers could argue that it came from someone else in the population,” she says.

Improving DNA evidence

Therefore, Kyla’s research focused on evaluating a new group of male-specific DNA regions, which are to be tested yet, to see if it would be a viable option for use in South Africa. 

“I achieved this by collecting DNA samples from men on campus, processing them to obtain DNA profiles, and then determining how well these regions can distinguish between the men. The results of my research demonstrate the potential of these DNA regions to improve the use of DNA evidence when investigating sexual assaults in South Africa,” says Kyla.

She believes her study can play a role in increasing the conviction rate of sexual offenders, which could lead to a reduction in South Africa’s alarmingly high rape statistic. 

“Everyone in South Africa is affected by this horrific crime in some way or another, so the benefits of this would be widespread,” she says.

Solving crimes

Although Kyla will one day pursue further studies, she is ready for the next stage in her life. “I am in the process of applying for jobs and getting ready to dive into the real world. I’ll definitely be pursuing a career working alongside police enforcement to solve criminal cases and convict perpetrators of such crimes. Working for the NYPD in the USA or Scotland Yard in the UK is the ultimate dream job,” she says.

“I chose my field not only because the forensics world absolutely fascinates me, but also because I want to make a difference. I want to play a role in getting justice for those affected by violent crimes. One simple process in a forensic scientist’s everyday routine could be a life changer for a victim of crime,” believes Kyla.

Every historical era presents its own challenges and creates its own leaders who take up the call to address those challenges.

This was expressed by Dr Nyefolo Malete who presented the Inaugural Memorial Lecture on 6 September 2014 at the Qwaqwa Campus. The lecture honoured the live of the Qwaqwa founder, Morena Paulus Mopeli Mokhachane.

Dr Malete said that Morena Mopeli played his part in history as a skilled negotiator, formidable team player and a liberator who held good human relations in high regard.

“Morena Mopeli lived at the time when Southern Africa was experiencing a moment of frustration and despair. It was faced with conflicts, battles, starvation and turmoil in preparation for a transformation that was to serve as the mirror of the political and social stage which existed until 1994,” Dr Malete said.

“He was a hopeful leader and thinker who played a critical role in assisting his brother Moshoeshoe to build and protect Lesotho where it was humanly possible. He participated in most of the negotiations with all the groups to create peace and protect the borders of Lesotho. He was a good, intelligent and formidable diplomat who was aware of his role as a leader. He was aware that he could influence the future through dialogue.”

Dr Malete said that Africa needs leaders like Mopeli. Leaders who can expand the capacity to remain open to possibilities and “envision a positive future in the face of uncertainty and to creatively construct pathways that can be embraced by all people who collectively seek to turn possibilities into reality.”

In attendance at the lecture were dignitaries from the Lesotho Royal House, the Free State Provincial Government and the Free State House of Traditional Leaders.
