Yup -- it is called a plea bargain.  The others probably turned on you and pled out as a dismissal or lesser charge/sentence.What do you mean by no physical evidence.  Accomplice testimony is direct first hand testimony -- which is evidence onto itself.  If you mean no fingerprints or other such items, first hand knowledge is often way better. You can call this direct evidence or others may deem it to be circumstantial evidence based on the lack of fingerprints.
