The dramatic escape of several research monkeys following a truck crash on a Mississippi interstate has cast a spotlight on the secretive animal research industry, exposing the opaque processes that keep crucial details from public scrutiny.
Three Rhesus macaques remain at large since Tuesday's incident, which saw a truck overturn in a rural area along Interstate 59, spilling wooden crates marked "live monkeys" into the tall grass. Search teams, equipped with masks, face shields and other protective gear, have since been combing nearby fields and woodlands for the missing primates. Five of the 21 macaques on board were killed during the search, though the local sheriff has not clarified how this occurred.
