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.

Culture contributes to success of UFS rugby teams

The University of the Free State (UFS) Rugby Club has succeeded once again in creating a culture of values.

Marius van Rensburg, Chairman of the UFS Rugby Club, believes this was one of the reasons why Kovsies had so many rugby successes this year.

The UFS knows that money, which is more abundant at bigger universities, won't change the club into a rugby force, but "there is something special here," he said.

Van Rensburg added that the success of Shimlas, who won the Varsity Cup for the first time, also helped to build a winning culture.

Seven finals

Seven of the UFS Rugby Club's teams played in finals during 2015.

Shimlas beat the Pukke in the Varsity Cup final at Shimla Park on the Bloemfontein Campus.

The Kovsie Young Guns (against Tukkies) and Vishuis (Mopanie from Tukkies) got stuck in Bloemfontein in Varsity Cup finals.

The Shimlas won Section B of the USSA tournament in Johannesburg (against Madibaz in the final).

A strong Irawa rugby team beat Shimlas in the City Cup.

The Kovsie Sevens team was crowned as the Varsity Champions in Cape Town after beating Tukkies in the final. The team was beaten by Maties in the final of the USSA Sevens tournament in George.

Shimlas lays foundation

According to Van Rensburg, the Varsity Cup triumph by Shimlas laid a good foundation.

“After what happened in the Varsity Cup, the winning culture kind of washed over the other teams,” he said.

He also thinks the 2015 successes didn't happen overnight, but that the club managed to bring back good values. He feels that Franco Smith, the former Shimlas coach who is the Cheetahs’ current coach, also played an important part.

Greater pressure in 2016

In 2016, the UFS's rugby teams will have a greater target on their backs.

Van Rensburg agrees that there will be greater pressure, but the structures are in place.

He feels that Varsity Cup success goes together with a touch of luck, of which Shimlas had some this year.

“Looking at the draw, Shimlas will play their first two matches away against Ikeys and Tukkies. Therefore, after two matches, one might have no league points, and that would place the team under immediate pressure.”
