There are several layers of questions in this posting, and it will be impossible to answer all of them without all of the facts. So, I highly recommend that you obtain legal representation. However, generally:
(1) Statements made at the scene of an accident or very shortly thereafter are almost always admissible in court as a "present sense impression", an "excited utterance" or as a statement of a party. So, for an individual to change their story later, which happens, hurts their credibility.
(2) When an injured person is in a second accident, the at-fault party is responsible for the injuries to the extent that they represent an aggravation of any pre existing condition. The person that caused the second accident is not responsible for previously existing injuries.
Please have the person that you know seek legal representation to untangle the many concerns tied up in your question.
This answer is offered for informational purposes only. It is not offered as, and does not constitute, legal advice. Laws vary widely from state to state. You should rely only on the advice given to you during a personal consultation by a local attorney who is thoroughly familiar with state laws and the area of practice in which your concern lies.
The admission of fault to the police officer is admissible as admissions against party interest and generally goes to the admission of negligence--but not liability. That is the defendant is admitting to have been careless, but you still have to prove that damages have resulted from that negligence- in effect the defendant is saying: "yes we were careless, but you were not injured or not injured to the extent you claim or your damages to the car was there before..." or other antics to that effect.
I hope this helps-

Admissions against interest made by an adverse party are exceptions to the hearsay rule and are admissible as evidence if and when any court case is brought against the adverse party.
Pre-existing medical conditions, prior accidents, prior workers compensation claims, subsequent car accidents or other subsequent injuries all can make any personal injury claim more complex. Personal injury attorneys who handle these claims on a regular basis know how to deal with these situations. Your friend should have a competent attorney representing his interests.
