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.

The success of netballers Adele Niemand (former Kovsie) and Karla Mostert (captain of the Kovsie netball team) continues - they represent Kovsies, the provincial Crinums, as well as the national SPAR Proteas as goal-keeper and goal defender, respectively. The UFS is also very proud of their inclusion in the national team for the upcoming 2015 World Cup in Australia.
 
On 6 June 2015, Niemand and Mostert played for the Free State Crinums, who overpowered the Gauteng Jaguars in the Brutal Fruit Netball Premier League (NPL). This win secured the championship title for the Crinums for the second time in a row.
 
“Our aim was to improve with each game. We did this throughout the league. The final game against the Jaguars was definitely our best game, so we are very satisfied. The NPL prepared us and gave us game time, which I think, is great preparation for the Diamond Challenge,” said Mostert.
 
Niemand and Mostert represented South Africa at the Diamond Challenge in Margate from 14 to 18 June 2015.
 
Prior to the event, Burta de Kock, Head Coach of the university’s team, said, “The Diamond Challenge in Margate will be hard, because Zambia, Uganda and Malawi want to be the best in Africa. But SA has enough brilliant players to do the trick for us, and we also have a great leader as captain.”
 
Niemand and Mostert form part of the national squad selected for the upcoming 2015 World Cup in Australia. Kovsie Lauren-Lee Christians from the UFS is the only non-travelling substitute for the World Cup. In their group, the team will compete from 7 to 16 August 2015 against Malawi, Singapore and Sri Lanka.
 
For the upcoming games against the world’s best in Sydney, Niemand has set a personal goal, namely to be the best by playing every game as if it's her last, and in so doing, aims to maintain the high standard of the team.
 
Their coach’s words of encouragement for the World Cup are: “Just go out with passion and enjoy every second. Never forget you are our CHAMPS!!”
 
The SPAR Proteas have indeed proven to be champions by beating Zambië 63 - 38 in the opening match of the challenge on 16 June 2015 at the UGU Sports Centre. They continued to beat Malawi convincingly by 43 - 33, and thrashed Uganda with a score of 56 - 39 to maintain their unbeaten run. The Proteas managed to uphold their lead to the end and thereby secured the tournament trophy win a win of 40 - 35.  In the first two games against Zambia and Malawi, Mostert and Niemand was respectively Player of the Match.
 
The UFS is also proud of Maryka Holtzhausen, a former Kovsie now captaining the Proteas. Ilze du Pisanie, also a former Kovsie, is the conditioning coach for the Proteas.
