There’s no credible evidence supporting this claim. Major outlets (AP, People, local CBS) confirm the tear-gas incident and hospitalizations. No verified reporting or court records link the mother in that case to a 2019 murder/robbery conviction, nor has any investigation found the story to be a hoax. This appears to be name-conflation and social-media speculation, not established fact.
If you can find verified court records or mainstream reporting that contradicts this, please share them.
