Direct answer: Several rhesus macaque monkeys escaped after a Tulane- affiliated transport truck overturned on a Mississippi highway in late October 2025. Most of the 21 monkeys on board were killed during the incident or in subsequent follow-up events, with at least one monkey captured alive and others shot or killed as authorities and residents searched the area. Context and details (based on recent reporting):
- The monkeys involved were rhesus macaques, commonly used in biomedical research, and were being transported from Tulane University’s facilities. The exact ownership of the animals outside Tulane’s custody was not fully clarified in initial reports.
- The crash occurred on Interstate 59 near Heidelberg, Mississippi, prompting an extensive search of surrounding fields and grassy areas. Wooden crates labeled “live animals” were seen scattered along the roadside.
- Reports indicate that several monkeys escaped into the rural area, with authorities later confirming captures of some and the deaths of most others. A homeowner reported encountering and shooting one of the monkeys, citing safety concerns for nearby children. Tulane officials stated the animals were not infectious at the time of transport, though rhesus macaques can carry diseases.
- Coverage from multiple outlets through early November 2025 notes ongoing inquiries into ownership, the total number involved, and the sequence of events following the overturn. Some outlets also discuss broader questions about the animal-research transport and safety protocols.
