The police will likely do further investigation. They may establish who was driving. The owner would be liable only of the owner was driving. Your evidence, standing alone is certainly enough to establish the identity of the vehicle that caused the damage. I do not believe it is enough to hold the owner liable. If the owner loaned the vehicle to someone, that person would be liable, but the owner's liability insurance would cover any damages the person caused (within the policy limits). If the vehicle were stolen, the thief would be responsible, and the owner's liability insurance would not cover it. If the owner's insurance company denies liability, (which the likely will, unless the police determine that the owner, or someone the owner's permission was driving), you should turn this in on your insurance. Otherwise, be prepared for a long drawn out ordeal in recovering your loss. Your insurance company will then file its own suit against the owner, if this is indicated from their investigation (and the helpful evidence you gathered), or it will sue the thief if one can be found.
