No kidding. These relatives all knew she was a raging alcoholic and totally unstable, but sent her off on this trip alone anyway, and now they’re mad a police — who had no clue as to this woman’s background — because they left her unattended for a few minutes and she killed herself!
Sadly, I think her family is much better off without her. It’s rare for people to actually get their alcoholism under control after becoming this far gone, and even in those rare cases nearly always involves a series of relapses along the way. The three kids would just have been repeatedly traumatized if they’d grown up with their mother around. The family should grieve, have a funeral, and move on. Dwelling on building a legal and PR(!) case that it’s all the police officers’ fault that she died is counterproductive — won’t bring her back, and will delay the process of moving on.
“Sadly, I think her family is much better off without her.”
In the long run you are probably correct, but I do feel very sorry for her children.
