According to ABC NET,
All 100 monkeys have been accounted for a day after a truck crash in the US state of Pennsylvania released several of the lab animals.
The monkeys had escaped following a collision between a truck and a pick-up on Friday local time, Pennsylvania State Police said.
But only one had remained unaccounted for as of Saturday morning, prompting the Pennsylvania Game Commission and other agencies to launch a search for it amid frigid weather.
Residents joined the police in their search for the missing monkeys in nearby forests.
