A baby chimp clings to its mother as she walks at Chimp Haven in Keithville, La., Tuesday, Feb. 19, 2013. An animal rights group has filed a federal complaint, Friday, June 17, 2022, against the national sanctuary for federally owned chimpanzees once used for experiments. A federal citation and Chimp Haven’s own reports about an escape and about deaths caused by fights among chimpanzees show the sanctuary’s care is poor, according to Stop Animal Exploitation Now.
