1) If you do not have an employment contract, you are an employee at will and may be fired at any time, for any reason--even an unfair or incorrect one. (If you do have an employment contract, its terms may be enforced if they help you.)2) The law does not require an employer to fire anyone or everyone involved in a alleged criminal incident or other workplace violation--the employer may decide who to fire.3) However, discrimination against a person (so, for example, choosing who to fire) on the basis of race is illegal. If you believe your firing may have been racially motivated, you may have a legal claim or cause of action, and should consult with an employment attorney.
