I lost my job today. they are accussing me of embellezment. They are going on the fact only that money was missing on the weekend I work

Based upon the information you have provided, it seems as if they are trying to make a circumstantial case against you for the embezzlement of money from your job.  A frequent tactic with this scenario is for the employer to promise not to pursue charges as long as you repay them and write a statement apologizing for your actions.  This usually leads to providing information against oneself and prosecution after that.  Feel free to contact me for further discussions
