Animal rights nonprofit PETA on Thursday is demanding proof the 43 primates that escaped from a research facility in Yemassee last year, were indeed recovered by the research facility as they claimed last week.

It’s been more than 2 months since 43 monkeys escaped from a research facility in South Carolina. On Friday it was announced that the final 4 missing primates were recaptured.

The final holdouts of a group of monkeys that escaped from a research facility in South Carolina over two months ago have been safely recaptured, the Yemassee Police Department announced on Friday.

Officials say they have recaptured the final four monkeys who escaped two months ago from a South Carolina compound that breeds them for medical research.

Finally, all 43 of the rhesus macaques have been found, according to the primate research facility in Yemassee, S.C., from which they fled in November.

The female rhesus macaques staged an escape from the Alpha Genesis Primate Research Center in South Carolina last year.
