Narrative:

We were heading east bound to a motor vehicle accident on the highway; all standard position calls made. Overhead the scene in a right hand turn at approximately 500 ft AGL heading roughly west to south east; I was looking and clearing to the right when the nurse in the rear called out that a helicopter had passed right beneath us by less than 100 ft heading south to north (from our right side). The nurse said he could see the aircraft was a [helicopter]. Even though I was looking in that direction I did not see the aircraft. Neither aircraft made any kind of avoiding climb descent or turn. The crew when they were on the ground questioned the local fire and police department and they said the aircraft was the county aircraft and that it had been in the local area just prior to our arrival. We think the pilot may have been 'rubber necking' the scene unaware of the possibility of EMS; news or police helicopters as it was fairly major event with multiple vehicles and EMS units on scene.
