On Friday, police spokesperson, Brigadier Motantsi Makhele said a farm employee found the bodies on Thursday around 4:30 pm.
The Free State police were alerted to the scene of the incident where two bodies were found on the farm and the third, in a river.
“The body in the river was found with a rock at the back of the head. Knobkerries suspected to have been used to kill victims, were seized from the scene,” Makhele added.
“According to the witness, [the] victims were seen at about 12:30 the same day with three police officers alleged to be from Lesotho and they were apparently following information about stock theft that occurred in Lesotho.
“All the victims are Lesotho citizens and they are estimated to be between the ages of 24 and 40.”
The reason behind the murder is not yet clear.
The Free State police are investigating the three cases of murder following the discovery of the bodies.
