Idaho parents sue federal government after cyanide trap injured their teen son, poisoned family dog

Boise, Idaho • An Idaho couple has sued the U.S. government, saying their teenage son still suffers headaches after a predator-killing trap that federal workers mistakenly placed near their home doused him with cyanide.

Mark and Theresa Mansfield of Pocatello filed the lawsuit Monday in U.S. District Court in Idaho seeking more than $75,000 in economic damages and more than $75,000 for pain and suffering.

Their son, Canyon Mansfield, then 14, was playing with his dog last year when he triggered the trap that the U.S. Department of Agriculture placed to kill coyotes. The dog named Casey started convulsing and then died.
