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.

Two players from the University of the Free State (UFS) will represent the country in the Fast5 Netball World Series in Melbourne, Australia.
Tanya Mostert and Lauren-Lee Christians will turn out for the Protea Fast5 team on 29 and 30 October. Fast5 is the shorter and faster version of netball.
Mostert was the UFS captain during the Varsity Netball tournament this year, after taking over the reins from her older sister, Karla Mostert. Tanya has to pass a final fitness test since suffering an injury earlier.

Lauren-Lee will captain this team

Christians represented Kovsies before, but this year she was above age to play in the Varsity tournament again. She represented South Africa’s Fast5 team in 2013 and 2014, but will this time be leading her country as captain "Down Under". She also was vice-captain of the Free State Crinums who won the Brutal Fruit Premier League in 2016.
Besides Christians and Mostert, three former Kovsies are also included in the Fast5 Netball team taking part in Melbourne. They are Vanes-Mari du Toit, Marlize de Bruin, and Fikile Mkhuzangwe.

Four national captains from UFS
With Christians’ selection as Fast5 captain, she became the latest of four Kovsies to be chosen as a national netball captain. All four South African teams – the Proteas, Fast5, U21, as well as the South African Universities team, were captained by Kovsies this year.
Maryka Holtzhausen, former UFS captain and currently assistant coach at the university, led the Proteas before suffering a knee injury. Alicia Puren led the SA U21 team, and Karla Mostert was captain of the South African Universities team that won the World Student Games in Miami, in the USA.
