Her smile used to brighten everyone’s day. She loved everyone unconditionally,” Haupt said.As the rain was pouring down, Haupt paused and watched as the children sobbed and held one another. He read Bible scripture in John 11:25.Balloons were released in a gesture of farewell.“As we release the balloons and they start to fade away, may we see it as a way of Kayla leaving us. We should never forget that she will always be in our hearts,” Haupt said.Earlier this week, Kayla’s teacher, Chantel Borissza, said the entire school was shocked and heartbroken at the news of Kayla's death. “We will always remember her as a kind, loving and zealously spirited child,” Borissza said.A counsellor at the school used a puppet show to explain the concept of death to Kayla’s classmates following her murder last week.(Iavan Pijoos, News24)Monty McCormack, 73, his son Kennith McCormack, 42, Kennith’s fiancée Marietjie Meyer and her daughter Kayla, were killed on a smallholding in Rodora, Randfontein, last week.The attack was assumed to have happened between Wednesday evening and the early hours of Thursday morning.Randfontein police spokesperson, Captain Appel Ernst, said the victims all sustained blunt force trauma.Haupt said they would plant a tree in her memory.“We have everything ready to plant the tree, but due to bad weather we won’t be able to do it today,” he said.
