One of the monkeys that escaped after a truck overturned in Mississippi last week was shot dead by a woman who said she feared for the safety of her children.
Jessica Bond Ferguson said she and other residents had been warned that the escaped monkeys carried diseases. "I did what any other mother would do to protect her children," she told the Associated Press.
The monkeys were being housed at Tulane University's National Biomedical Research Center in New Orleans, Louisiana, for scientific research purposes and escaped last weekend while being transported.
Officials from the university said that the monkeys did not have "any infectious agent".
The 35-year-old mother of five said her 16-year-old son alerted her to a monkey in their backyard in Mississippi.
