Kim and her younger brother Ken left their home on 4 January to go and play with friends. They were last seen when they got off the tram at the Schijnpoortweg. What happen to the children them remains a mystery to this day.
Kim’s body was found just over a month later on 11 February in Antwerp’s Asiadok. An examination of her body showed that had been abused before being murdered. The identity of the killer remains a mystery. Ken has never been found and was declared dead by the Civil Court in Antwerp in 2004, 20 years after his disappearance.
The memorial stone was erected in 1997 near to the place where Kim Heyrman’s body was found. Each year on 4 January relatives and sympathisers hold a remembrance ceremony not just for Kim and Ken, but also for all the missing children that have never been found.
