opening of detective films and series

The opening of a detective film or series usually follows the same basic pattern of the audience being shown the crime being committed (usually a murder), where you cant see who's done it, then someone turning up to find the dead body and then the main detectives turning up on the scene to examine the body with the forensics team.

the opening 5 minutes of this episode of Law and Order: UK shows an innocent father and daughter finding a burning house with people trying to get out through the windows which are bared. This is the innocent bystander stumbling upon the body. The enigma within the audience is to weather the fire had been started by a criminal or if it was simply an accident. The scene then changes to the fireman team and the forensics team on the scene as the main detectives turn up to look at the body and the burned house before the credits.

I will try to use this pattern in my opening sequence by following the same rules with the audience seeing someone being attacked and asking why. Then the scene will change to the main detective turning up and casing the scene whilst working with the forensics team.
