Authorities in Jasper County, Mississippi, are asking residents to avoid contact with several Rhesus monkeys that escaped after a truck transporting the animals from Tulane University overturned on Interstate 59 early Tuesday morning.
Crash Releases Research Animals
According to Jasper County Sheriff Randy Johnson, the truck was hauling 21 monkeys to a testing facility in Florida when it crashed near the 117-mile marker just north of Heidelberg. Several of the animals escaped the wreck.

Public Warned Not to Approach
Sheriff Johnson said most of the monkeys have since been accounted for, though at least one remained uncontained as of the latest update. Officials are urging anyone who spots one of the animals not to approach or attempt to capture it, and to call 911 immediately instead.
“Do not try to capture or touch these monkeys,” Sheriff Johnson said. “They can be aggressive and are carriers of diseases including hepatitis C, herpes, and COVID.”
Some Animals Euthanized for Safety
Authorities confirmed that five of the escaped monkeys were euthanized due to safety concerns. Tulane University has sent crews to help retrieve the remaining animals and assist with cleanup at the crash site.
Multi-Agency Response Underway
The Mississippi Department of Wildlife, Fisheries and Parks joined local law enforcement to help manage the scene, and officials are coordinating with an animal disposal company. The highway remains partially restricted while cleanup efforts continue.
Ongoing Caution Urged
Sheriff Johnson reiterated that residents in the Heidelberg area and along I-59 should remain cautious until every animal is accounted for. “If you see one, do not approach it — report it,” he said. Officials say containment and public safety remain the top priorities as recovery work continues.
