So sorry for your loss Carlos. That tank was pimpin too. I feel for you bro.
As for the nimrod of a landlord who lives with you, he seems like the type that won't even know what hit him if something happened so don't waste your time and effort. You're already taking the right move by moving out ASAP. Leaving doors unlocked is not cool at all in my book, especially because you have your family inside while you're gone.
Don't quit but use this opportunity to start fresh. Make your next tank even better. You got the skill so it'll be cake.
Keep your head up man.
