A collision between a dump truck and a trailer carrying about 100 monkeys on Friday scattered crates of live animals across a road in Montour County, Pennsylvania, and prompted a search for a "small number of monkeys," the state police said.

One monkey was unaccounted for on Saturday morning, according to a tweet from the Pennsylvania State Police (PSP) Troop F.

Temperatures were below freezing on Friday night.
