I think the men (and I use that term loosely) have/had manual labor type day jobs & the wives do not work. MWK, WWH, DH nor DK own any residential property in Mobile or Baldwin counties and their primary residences are rentals (according to county property records).
I believe DH may have been on disability (bad back and/or heart issues) at the time of his death. I think he probably earned some extra cash from pharmaceutical sales (cough, cough).
I would not be surprised if they earned extra cash with photo & video sales but I also think if such things exist they may have just kept it in-house for personal use. (barf). I don't see them being technologically savvy enough to know how to use TOR or the underbelly of the Internet to facilitate such transfers and especially not involving financial transactions. Can't really walk up to your neighbor and ask, "hey bob, nice weather we are havin'. Wanna buy some underage




?"
So basically no... No way in H E double hockey sticks do I think DK or MWK have the personal financial means to pay his for his bail, defense attorney, daily electronic monitoring or court fees...
As a former Risk Manager... A life insurance policy that will pay out in the event of suicide is extremely rare & the premiums are very expensive... Additionally - DH was obese, had heart problems, drank & was a smoker so even IF he could get a basic life insurance policy the premium would be astronomical. (BTW - I don't see DH being a viable organ donor. When this was mentioned I thought to myself, "um yeah... the only willing recipients would be for research or academic purposes - not for any transplants.")
The chances of DH even having private medical insurance would also have been unlikely given his health but if he did those premiums would cost a fortune. I just don't see them paying expensive premiums for life insurance on top of thousands of dollars for health insurance even if they could afford it.
I don't think sound financial planning, investments and healthy lifestyles are/were at the top of the Holland's list of priorities.
