Well I have made my inquiries in the primary question.
Anyway, my question is this: will it help my defense if the post mortem reveals that this guy was in fact under the influence of drugs and alcohol and we could arise any doubt and that may be he cycled in front of the vehicle and may be caused his own death. He had no helmet, reflective clothing, lights on bicycle.
Also BEFORE my lawyer was served with disclosure of some evidence which was the dna forensics examination of the vehicle I was told by my sister that when she had went to the station she was told by the investigating officer that traces of blood had been found on the vehicle. Could this help my defense at all? Also, in interview the same said officer lied about some of the phone record evidence. Could this help anything?
