An unfortunate discovery of a Navy veteran's passing.

Honestly, this story just completely baffles us. A Navy veteran, Rodney White, was found dead in his Dallas-area apartment last week. The worst part is- he had been dead approximately three years medical examiners said.Let's talk about some of the pieces of information given...
The family reported they did not have the funds to hire a private investigator and they had contacted the police almost immediately after he stopped contacting them. But honestly, it still baffles us as a child to our own parents that not a single family member had the ability after years to further investigate this themselves. (We would personally be stacking bodies looking for answers if either of our parents went missing, so attempting to see this from the family's side is difficult.)The police had also told the family that because White traveled frequently for unknown periods of time, they could not file a missing persons report. But, couldn't they have still done a health and welfare? The medical examiner stated there is no evidence of foul play and we wholeheartedly believe that may be true, but it still leaves us asking so many questions.How could this have happened? It wasn't three months, it was three years. The complex didn't have to perform any checks at all within that time? When we had an apartment, the maintenance personnel would leave notes almost monthly stating they had to replace air filters, check this or that, and so forth.Ultimately, we do hope the family finds peace in finally knowing what happened to their loved one. But we hope EVERYONE can take this as a lesson to never take no for an answer. And if your loved one is missing for YEARS- fight. Someone knows something and answers can be found.
