There are going to be more and more of these lawsuits as the silent gen and boomers pass away. This case is a bit odd, since the named beneficiary is a sex worker, so he'll be judged for that; but likely the relatives left out of the will are going to be seen as money-grubbing, and not truly believing that their aunt had been manipulated.
My guess is the aunt had dementia and had a number of people taking advantage of her in her final years, like my mom did.
