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.

UFS experimental farm to be redesigned as a training facility

The Faculty of Natural and Agricultural Sciences of the University of the Free State will soon sign a tri-partite cooperation agreement with the National African Farmers Union (NAFU) and the Mangaung Local Municipality with the aim of providing training and mentorship to small-scale and emerging farmers, including those recently settled under the on-going land redistribution programme.

The agreement is part of the Faculty’s strategic plan to support the on-going reform process in the country, of which Black Economic Empowerment in Agriculture (Agri-BEE) is an important part. The Free State Provincial Department of Agriculture is also actively supporting this initiative.

Under the plan, the Faculty is redesigning its experimental farm, located about 12 kilometers south of Bloemfontein, as a training facility to build up skills in among others broiler and egg production, dairy farming, animal husbandry, piggery, sheep and goat production. The idea is to introduce a comprehensive package that empowers the small and emerging farmers and the local communities adjoining the farms through simultaneous investments in research, extension, and practical agricultural training.

Learnerships are also being drawn up to provide productive skills in order to contribute to addressing the national skills gap and enhancing opportunities for both self and wage employment.

The residents of the adjoining informal settlement known as Mangaung Phase II where unemployment is currently at extremely high levels are primary targets of this component of the project. The Faculty intends for this project to service the farming communities of the Free State Province and gradually spread to other Provinces in the country.

Having recognised this training programme as a potential instrument for achieving “a united and prosperous agricultural sector”, the Free State Legislature has shown considerable interest in the programme.

Following a preparatory visit to the farms by the Agriculture Committee of the Free State Legislature a request was made to the Faculty to host a larger visit by the Legislative Committees of the Free State, North West and Eastern Cape Provincial Legislatures on Monday 25 October 2004 and present details of the training programme.

The President of NAFU in the Free State Province, Mr Nox Nonkonyana, the Dean of the Faculty of Natural and Agricultural Sciences, Prof Herman van Schalkwyk, the Chair of the Mangaung Municipal Portfolio for Agriculture and Rural Development, Councilor Thami Stander, and the Chairperson of the Free State Legislative Committee on Agriculture, Mr M Nketu, will address the Legislators during the occasion.
