Cilliers’ husband, Dr Bernard Cilliers (61), was killed during the attack on their farm on Friday, 29 January.

“According to the SA Constitution everyone has the right to a safe environment, but it is not practically possible for the police to keep everyone safe at all times. We request farmers to also take responsibility for their own safety, to join safety structures and to actively take part in these structures,” said Esterhuize.
FSA said it welcomed the announcement by the SAPS that farm attacks and murders would henceforth be considered as priority crimes.
