“I just received a money order in the mail from someone that I do not know, and I am unemployed and have been unemployed for almost two years. Also, I just received an email this morning, stating that I need to cash the money order, send portions of it to two specific people and keep 10% of it to myself. Should I do as the email said, rip up the money order or send it back?”
You should contact the postmaster general in your area, and the police department. This is almost certainly an illegal activity in which the instigator is trying to involve you.
