I tend to think he purchased a term life policy when Lara was small, and probably put it with family papers somewhere and forgot about it.
The purchase of life insurance BEFORE he retired that same year and within a year or two before he disappeared would be a huge red flag on many levels, I think.
However, there is one point that makes me wonder if he did get a policy issued. We know he apparently did not have annual medical wellness physicals. It has been stated that he had no known health issues without a caveat that he didn't have yearly medical assessments. A hypothesis can be made that the physical exam referred to as confirming his health was related to the issuance of a life insurance policy. I don't know, of course, but I do remember performing these thorough physical exams for a national insurance company when I was very young because they paid RNs quite well.
I think it would have been extremely imprudent if he had even attempted to acquire life insurance for a period of a year before he disappeared IF his departure was planned. This time frame also clashes with his needs post- retirement ( assuming he was planning on traveling with Patty, etc. after retirement).
Next, what about Patty?
Is it reasonable to think he didn't plan any type of annuity for her in the event of his death?
I don't know that he spent one dime of his savings on insurance policies but the time frame of his upcoming retirement may have made a difference. I remember how my dad, a State employee, and my mother, had to make difficult decisions regarding health and life insurance coverage continuance and supplementation when my dad retired at an age slightly younger than Ray's age. To their extreme disadvantages, they dropped all group coverage.
