How can i call the 'col' object from the Update function?

There’s the code:

var sound : AudioClip;

function Update() {


}

function OnTriggerEnter(col : Collider) {


	if(col.tag == "Rabbit") { 
	
		col.GetComponent(RabbitS).enabled = false;
		col.GetComponent(RabbitS).health = 0;
		gameObject.audio.PlayOneShot(sound);
		gameObject.animation.Play("Trap");
		transform.FindChild("GameObject").collider.enabled = false;
	
	}
	
	
}

I want to delete the ‘col’ gameObject, but i don’t know how to call it.

col.gameObject

I should have rejected this on principle. Do you know there is a massive amount of documentation for unity? It can be found using google
