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 one implies dreams of victory; the name of the other means ‘bringers of honey’ in the Khoisan language.

With these unique names, two new residences, House ConLaurês and House Outeniqua, will create new memories for generations of Kovsie students. The two residences were officially opened on the Bloemfontein Campus of the University of the Free State, bringing the number of junior residences on the campus to 19.

Celebrating the new addition to residence life, Mr Quintin Koetaan, Director: Housing and Residence Affairs, told residents of House ConLaurês and House Outeniqua that they were part of history. He told guests that the residences will provide accommodation for a new generation of students and encouraged residents to breathe life into their respective abodes.

“Nobody thought that two residences could be built in a year,” he said about the short time between the planning and opening of the residences in January this year. The two residences welcomed 250 students each, with male and female students living under one roof, but in separate units.

Prof Jonathan Jansen, Vice-Chancellor and Rector, praised Koetaan and his team, as well as the developers, saying they have done something completely different on the campus. He said the two residences will create a place which students can call home. “It will create a place not just to eat and sleep, but also to learn. It will create memories for many years to come.”

Mr Rudi Buys, Dean: Student Affairs, said House ConLaurês and House Outeniqua is much more than simply residences. “It’s about the university putting its heart out there, showing what can be done.” He told guests that representatives from other universities and the Department of Higher Education and Training have visited the UFS to see what is being done here.
