call you insurance give them the license plate number they will track it down for you, why bother you pay insurance for the service, why wait your time going looking for this guy.
It\'s against the law for law enforcement officer or DMV..etc to release any personal information to you. They have no proof of knowing you telling the truth or just want to look up information. If they realease any information to you, they will be reliable for it.
Just call your insurance they will handle it.
Police officer will not take a report in this case, since it was after the fact, well they might write one for you not will not investigate anything, unless it was a hit and run. But in this case you have the other party information except for the phone number. It\'s was your fault for not calling them in the first place. They will refer you to the insurance company.
It\'s also your fault for not taking the guy address, driver license number, day of birth...and so on.
