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.

The last of 43 escaped monkeys has returned to the Alpha Genesis research lab in Yemassee, S.C., nearly three months after an attendant accidentally left two doors unsecured.

The group of 43 young primates escaped at the beginning of November following an alleged staff error. It was reported one of their usual caretakers failed to secure two doors behind her. A week ago, only three of the monkeys remained outside of the facility,
