Are you 100% sure police withhold letters? I have multiple friends abroad who may not even know of my passing if it isn't for letters. Planning to ctb wednesday and was banking on my parents sending out the letters... May focus more on effectiveness and send the letters out tomorrow because of this. Plz get back to me if I can thanks.
I knew someone with a family member who had this happen, they left notes/letters and they were taken for nearly a year (the person I knew only got to read one of the letters somewhat because they were first on the scene, but that one they read was also taken), then I researched it further and found that it's common, that is what I'm basing my statements off of. But I cannot say for every police department, they don't all operate the same and it also depends how suspicious your suicide is going to come across as.
Another thing: location, I won't give mine away but your mileage may vary based upon where in the world you are located.
Are you planning on leaving them all for your parents?
I assume your parents aren't aware of your plans so they can't contain the letters somewhere safe until they are sent out.
I think this is one of the reasons some here opt for scheduled emails or delayed texts.
If you are sure of your plans and don't foresee any roadblocks, you could just send them out beforehand and I'm sure they would not be delivered until after your passing. (But then you might feel bound by the fact that they are sent, and then if you change your mind or realize it's too soon, you might feel pressured to go ahead anyway, which wouldn't be a very good or fair situation for yourself.)
Or if you trust your parents not to hand them over to police, you could stash them all somewhere the cops would be unlikely to look, but somewhere your parents surely will, maybe even sending one delayed text or email (if possible on your end) to hint at the location of these letters.
Could make copies too and put them in separate places, just to be safe (unless you want them to be handwritten originals.)
When my bf ctb he left letters for me and each of his kids. We got our letters without delay. But he did leave the letters at his home and he ctb at his dad's home. I think the police would only take what is at the crime scene. The police actually asked my bf dad if he wanted the gun or any of the soiled items but his dad asked them to destroy everything. It was a clear cut suicide.
Yup, I believe in all the cases that I've come to know about, all letters obtained were usually from the crime scene itself or at the same location.
As long as letters found elsewhere aren't driven straight to the station, a separate location can be a decent idea.
