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.

State of our campuses: UFS campuses closed until Friday 23 September 2016
2016-09-20

After careful assessment of the situation on the Bloemfontein, Qwaqwa, and South Campuses of the University of the Free State (UFS), and engagement with the Student Representative Council (SRC), the senior leadership decided this morning to close all its campuses until Friday 23 September 2016.

All academic and administrative services on the three campuses have therefore been suspended and will resume again on Monday 26 September 2016. This means that no academic and administrative services will be available and no lectures and/or tests will take place on the three campuses for the rest of the week.

This decision was made after all academic activities were suspended on the Bloemfontein Campus yesterday afternoon because of a growing unease and disruption of some academic activities by groups of students, resulting from yesterday morning’s announcement on tuition fees by the Minister of Higher Education and Training, Dr Blade Nzimande. Although the university management is in favour of peaceful protests, it condemns these disruptions, especially as it took place during an important time in the academic calendar.

The decision to suspend academic and administrative services for the rest of this week was taken with caution, as it will ensure the safety of staff, students, and university property. It will also assist the university management in maintaining stability on the campuses.

Adjustments will be made to the teaching calendar, and students are requested to obtain this information from their respective faculties. No student will be disadvantaged in terms of tests or assignments as a result of the unfortunate closure of the university for the rest of the week.
