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 2017/2018 Student Representative Council (SRC) elections on the Qwaqwa Campus of the University of the Free State (UFS) have been declared free, fair, and credible. This was announced by the Chairperson of the institutional Independent Electoral Agency (IEA), Grey Magaiza, during the official announcement of the results and the hand-over ceremony held on 4 September 2017. 

“We had an average voter turnout of 52% per elective portfolio, thus making it arguably one of the highest in the country. Compared to last year, there was a 15% increase notwithstanding the 23% increase in the student population,” he said.  
In congratulating the newly-elected SRC, the Director of Student Affairs, Temba Hlasho, challenged the student leaders to leave the campus intact and fully sustainable for future generations.
“You are now faced with the mammoth task of understanding your role in developing an ethical and moral leadership that will help to sustain the university academically, financially, and beyond.”
In his response, the new SRC President, Masopha Hlalele, acknowledged the role played by the previous SRC, and said they were prepared to usher in a new phase of turning each student into a proud ambassador of the campus.

“We will be ushering in a new phase where all students will be the focus of the SRC. This will be a phase where students will not discriminate against each other, but appreciate each other’s differences and become ambassadors,” he said.

The South African Students’ Congress (Sasco) won all seven elective seats with an average of 62.5%.

Elective portfolios:

President: Masopha Hlalele 
Deputy President: Sakhile Mnguni 
Secretary General:  Mawande Mazibuko 
Treasurer General:  Mafusi Mosia
