Most news outlets were reporting that he had gone into “rehab” not specifying what kind of rehab. Along with the news he had stolen money from the law firm, I thought possibly he might have gone into gambling rehab. If he has a gambling addiction he could have been in deep debt with the wrong people who may have murdered his wife and son. I have only seen one report that mentions drug rehab.
Quite right; even now, there’s a bit of mob involvement in high-end gambling.
