I was thinking about my cousin...he had died December 23rd, 1999...he was found in Florida floating on his side, drowned...ever since he had died I thought that maybe he was killed...I was thinking about investigating his death when I got older...I think it'd be a good idea...I dunno...what do you guys think?
I dont know your family but you may get some resistance from them, since its been 5 years already, my guess is that they are trying to move on and I dont think they would appreciate it to go and dig up all the bad memories again for (what they will probably think) a useless investigation.
