An ex-worker at a Houston home decor store has pleaded guilty in a $2 million insurance scam in which customers intentionally fell and then filed claims. Sandra Johnson of Katy faces up to 20 years in prison. Prosecutors on Tuesday announced the former claims manager at a Garden Ridge Pottery store pleaded guilty to receiving kickbacks in the money laundering conspiracy. The case involved more than two dozen false claims approved by Johnson and settlements topping $2 million.
