Hmm, I am not sure what you can do for this, but here is a rough coding scenario.

A player escapes, check the players position, or simple use playertopoint.

When that player is at that point, or their position is there, where you checked (GetPlayerPos / PlayerToPoint), play the sound, and send an alert to all online cops, and some players, if you want: (Create a loop for both the cops, and players if you want. PlayerPlaySound(loop, sound), SendClientMessage).

Good luck.
