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.

Mathatha Tsedu to deliver King Moshoeshoe lecture
2009-06-29

Mathatha Tsedu 
The former Editor of City Press, Mathatha Tsedu, will deliver the Second King Moshoeshoe Memorial Lecture at the University of the Free State in Bloemfontein on Wednesday, 9 September 2009.

The King Moshoeshoe Memorial Lecture series are an initiative of the University of the Free State to honour the leadership legacy of King Moshoeshoe I, founder of the Basotho nation. The lecture series aim to provide a platform for debate about the key challenges of nation-building, reconciliation and leadership facing our country and the African continent.

In 2004 the UFS produced a documentary on the life of King Moshoeshoe I as part of the project to pay tribute to this great African leader. The documentary was screened numerous times on SABC TV.

Later in 2006, the inaugural King Moshoeshoe Memorial Lecture was delivered by Prof Njabulo Ndebele, former vice-chancellor of the University of Cape Town.

Mr Tsedu is one of South Africa’s foremost journalists and social commentators. He will speak on the topic, “When globalisation ties the fate of the Maluti to that of the ice caps on the Alps, what does Morena Moshoeshoe teach us about leadership today?”

Mr Tsedu has received several awards, including the Nat Nakasa Award for Courageous Journalism in 2000 as well as the Shanduka Lifetime Achievers Award in 2007.

A graduate of the University of the Witwatersrand, he started his career in journalism as a bureau reporter for the Sowetan in 1978 responsible for the then Northern Transvaal. Later Mr Tsedu became Political Editor of the Sowetan, the Deputy Editor of The Star as well as the Deputy Editor of the Sunday Independent and Deputy Chief Executive of SABC News.

He has also been the Editor of two major Sunday newspapers, the Sunday Times and City Press and is currently the Head of the Journalism Academy at the Media24 group.

Mr Tsedu is the Chairperson of The African Editors Forum and a Council Member of the South African National Editors’ Forum (SANEF). He has addressed various organisations on journalism in South Africa, including the International Federation of Journalists; the International Confederation of Free Trade Unions; the Botswana Journalist Association; the Zimbabwe Union of Journalists; the Kenya Union of Journalists; and the Union of African Journalists.

He was an active trade unionist and national executive member of the Media Workers’ Association of South Africa. He was detained several times, banned and restricted to Seshego in the Northern Province from 1981 to 1986.

Mr Tsedu is also a short story writer with several of his stories published in various magazines. He was awarded a prestigious Nieman Fellowship in 1996/97 to study at Harvard University in the United States of America.
