Apology Letter For Embezzlement
Dear {Recipient},
Please accept my deepest apologies for embezzling from the company while I served as {role} from {date} to {date}. {Cashing customer checks/overbilling customers/stealing products/something else} was probably the last thing you thought I'd do, and I'm sorry for breaking your immense trust in me.
You can expect my full cooperation in whatever legal action {the board/management} decides to take regarding this matter. Again, I'm very sorry for what I did and for letting everybody down.
Sincerely,
{Your Name}
