Cornelius and Marsh were students at the nearby University of Stellenbosch, according to local media reports.

Rector Professor Wim de Villiers told The South African that the university community was left shocked after the incident.

He said: 'Our campus community is shocked by this senseless death and our hearts go out to the family and friends of the student who lost her life, as well as the student who was injured.'

Cornelius's family released a statement following news of her death.

'It is with great shock and sadness that we learnt of the tragic death of our beloved Hannah Cornelius,' the statement from her uncle, Andries Cornelius, said. 'The family does not have all the facts surrounding her death as yet.

'They have been advised to await the full report from the relevant authorities so as not to prejudice the investigation.

'Hannah was studying a degree in humanities at the University of Stellenbosch. At the time of her death, she was 21 years old.

'The amount of support the family has been receiving is testimony to what an amazing, loving and beautiful person our Hannah was. The family has requested that their privacy be respected in this very difficult time.'

Her 18-year-old brother, who has severe autism, has not been able to comprehend his sister's death, Andreis Cornelius said.

"I assume he will never know. You can tell him what happened but he will never stop asking when she's coming back," he said.

A funeral service for Cornelius, who was a second-year humanities student, is being held at Fish Hoek NG Church at 11am on Friday.

Cornelius is said to have been an 'exceptional pianist' and excelled in high school.
