Key points
- Forty-three rhesus monkeys escaped from a testing facility in South Carolina earlier this week.
- The primates escaped after an employee failed to fully lock the door after feeding and checking on them.
- One has been recovered, while many of the others are found jumping back and forth over the fence a few feet from the facility.
Many of the others are still within a few feet of the property, jumping back and forth over the facility's fence, police said in a statement.
How did the monkeys get loose?
“It's really a kind of follow-the-leader. You see one person go and the others go,” Greg Westergaard, CEO of Alpha Genesis, said at the time.
“The handlers know them well and can usually get them back with fruit or a small treat,” Yemassee Police Chief Gregory Alexander told the Associated Press.

What are the monkeys doing?
The primates continued to communicate with their companions at the facility on Saturday, which is a positive sign, the police statement said.

Westergaard said efforts to recover all the animals will continue through the weekend and for as long as necessary.
Alpha Genesis, U.S. federal health officials and police all said the monkeys pose no risk to public health.
However, local residents were advised to close windows and doors so that the monkeys could not find shelter.
Who is the company responsible?
Alpha Genesis supplies primates for research around the world at its facility in Yemassee, about 50 miles northeast of Savannah, Georgia, according to its website.
Alpha Genesis employees had “monitored the primates” and “worked to entice them with food,” police said shortly after their escape. Source: Getty, Anadolu / Peter Zay
The facility breeds the monkeys to sell to medical and other researchers.
Officials said 26 primates escaped from the Yemassee facility in 2014, and another 19 escaped in 2016.
