I used to live in KC and know the type of Indepedence trash this woman is. I bet she's running a meth lab in her kitched.
Extreme duress used to be applied to people who were ~tortured~ into confessing to crimes. You know.... breaking people's fingers, threatening family members, electrical probes. Now 'extreme duress' is moving somewhere where they don't allow pets? That's who 90% of the dogs signed over to shelters came from.
Look, don't make me minimize the man's situation. I know his situation is hard.... Everything lost to a hurricane, he is forced to relocate with family somewhere else. One of the choices he made, that he now regrets, was to sign over the dog, but 'stressful' is not 'extreme duress' in terms of the law. All he's got is a good emotional case. She ~should~ relent and give the dog back, but you won't get there bey twisting the law, that's the best way to ~lose~.
