The remains of at least two, perhaps three, poachers were found on Tuesday at the Sibuya Game Reserve in South Africa’s Eastern Cape Province, alongside equipment used to kill and dehorn rhinos.

At about 4:30 p.m. on Tuesday, a field guide found one head, numerous limbs, a high-powered rifle an axe, and three pairs of empty shoes.

“At this stage it is not clear exactly how many poachers were killed but the police forensic team continue to investigate,” Nick Fox, owner of the Sibuya Game Reserve, said in a statement, released on Facebook. Police have been patrolling the reserve via helicopter and have yet to find any other poachers.

It is suspected that at some point Sunday night or Monday morning, the poachers broke into the reserve with the intent to hunt and de-horn rhinos. But they wandered into a pride of six lions and were killed.

“Whilst we are saddened at any loss of life the poachers came here to kill our animals and this sends out a very clear message to any other poachers that you will not always be the winner,” Fox told the Daily Mail.

So far this year, more than nine rhinos have been killed in the Eastern Cape province, according to the BBC. More than 1,000 rhinos were poached in South Africa last year.

Africa is seeing a growth of rhino poachers to keep up with demand for rhino horn in parts of China and Vietnam. The horn is prized for display and as a rumored traditional Chinese medicine.
