I have sympathy for your family members. I (obviously) have no idea about the details of that situation, but since a violent crime can't be committed over the internet via a chat app, there ought to be physical evidence of that crime, no? If there's some sort of conspiracy element to that, I can see how chat logs might be useful. But attempting to require folks to provide information they don't have (as is the case here) is a fruitless endeavor. What solution would you suggest? Get rid of encryption? Force providers to collect the contents of their users' computers and phones? While, as I said, I sympathize with your family members (and you), such an outcome doesn't justify taking away everyone's privacy. Especially since the vast majority of people are decent, law-abiding folks. I get that your experiences and the pain they've caused won't allow you to see things differently, but privacy is important, and I for one, won't give mine up without a fight.
