South African authorities are investigating the deaths of two tourists found in Kruger National Park after they failed to return to their lodge. Police say the pair—one identified as a 71-year-old man and a woman whose age has not been disclosed—did not return on Wednesday evening, prompting a search. Other tourists later discovered the bodies on Friday afternoon in a river within the park. Police report that the man has stab wounds and that the woman’s body shows bruising. Authorities say the tourists’ car is missing, and they are treating the case as suspicious while pursuing leads. In response to the incident, security measures in and around the park are increased. The investigation is ongoing, with police continuing to determine the circumstances surrounding the deaths, the cause of injuries, and where the missing vehicle may be. Media reports also note that the heightened security is intended to reassure visitors and prevent further incidents as authorities work through the facts of the case.
