The search for 43 rhesus macaque monkeys that escaped from a South Carolina research facility west of Charleston came to an end on Friday. The Yemassee Police Department announced that the last of the fugitive primates had been safely recaptured, concluding a months-long effort involving local authorities, research staff, and the community.
The Escape and Initial Efforts
The monkeys escaped in early November from the Alpha Genesis Primate Research Facility after a caretaker failed to secure the doors, according to the facility’s CEO, Greg Westergaard. Alpha Genesis specializes in research projects involving rhesus, cynomolgus, and capuchin monkeys for government, university, and private industry clients.
The escape set off an extensive search in the wooded areas surrounding the Yemassee facility. Residents were urged to keep doors and windows closed and avoid interacting with the monkeys, including refraining from flying drones near them.
About the Rhesus Macaque Monkeys
Rhesus macaques are small primates of Chinese or Indian origin that thrive in various climates and habitats. According to the Wisconsin National Primate Research Center:
- Male macaques weigh around 17 pounds and are approximately 21 inches tall.
- Females are smaller, weighing about 12 pounds and standing 18 inches tall.
These agile primates are known for their ability to adapt, making their recapture a challenging process.
Tracking and Capturing the Monkeys
Alpha Genesis staff employed humane traps and food as bait to lure the monkeys. Police used thermal imaging technology to monitor their movements. Despite these efforts, the monkeys proved elusive, with the first captured on November 9, just two days after their escape.
By November 17, only eight monkeys remained at large. CEO Greg Westergaard provided updates, describing the monkeys as being in good health and energetically running and playing in the trees.
The final four macaques evaded capture for over two months, staying close to the facility.
Final Breakthrough
The last monkey was safely recaptured on Friday, following the earlier capture of the other three that week. All four were found in good health, bringing relief to local authorities and Alpha Genesis staff.
“This was a real team and community effort,” said Westergaard, thanking local residents for their patience and support during the prolonged search.
Community Impact
The escape raised concerns among Yemassee residents, who were advised to remain cautious during the search. Despite the potential risks, the community rallied together, with many assisting in keeping the monkeys safe and supporting recovery efforts.
The successful recapture of all 43 rhesus macaque monkeys marks the end of a unique and challenging incident for the Yemassee community. While the escape posed logistical and safety concerns, it highlighted the importance of collaboration between the facility, local authorities, and residents. Thanks to their combined efforts, the monkeys are back in safe custody.
