Monkeys
On January 21, 2022 a trailer carrying 100 monkeys on I-80 in Danville, Pennsylvania collided with a dump truck spilling monkeys onto the roadway.
At least 4 monkeys got loose and were eventually captured. Unfortunately 3 of the monkeys had to be euthanized.
The cynomolgus monkeys can cost up to $10,000 each and are used in medical research.
