How do i access another game object and destroy it?

I've been working on this script for sometime now, where i have a body collider and a head collider. i've gotten the script to recognize the separate hits by debug logging it, but when i put in Destroy (gameObject); i think it destroys something on my character because i no longer can shoot or get the sounds. i was using the rigid body on one , but a tag on the head. any advise or another way to go about it would be greatly appreciated. please, i'm not necessarily a noob, but not far from it, so if you could explain it in the layman's term i would appreciate that just as well.

    var range: float = 1000;
 var force: float = 1000;
 var clip : int   = 20;
 var bulletsPerClip:int  = 60;
 var reloadTime :float  = 3.3;
 var bulletsLeft: int = 0;
 var shootTimer: float = 0;
 var shootCooler: float = 0.9;
 var shootAudio: AudioClip;
 var reloadAudio: AudioClip;
 var damage: int = 50;  
 
 

I can hit each collider and it will debug properly,but how do i destroy the whole gameObject ...parent and child..

 function Start () 
 {
 
     bulletsLeft = bulletsPerClip;
 
 
 }
 
 function Update () 
 {
     if(shootTimer > 0)
     {
         shootTimer -= Time.deltaTime;
     }
     
     if(shootTimer < 0)
     {
         shootTimer = 0;
     }
     
     if(Input.GetMouseButton(0) && bulletsLeft)
     {
         if(shootTimer == 0)
         {
             
         
         PlayShootAudio();
         RayShoot();
         
         shootTimer = shootCooler;
         
         }
     }
 }
 
 function RayShoot()
 {
     var hit: RaycastHit;
     var directionRay = transform.TransformDirection(Vector3.forward);
     Debug.DrawRay(transform.position, directionRay * range, Color.red);
     
     
     if(Physics.Raycast(transform.position, directionRay, hit, range))
     {
         if(hit.collider.gameObject.name == GameObject.FindWithTag("Body").gameObject.name)
         //if(gameObject.FindWithTag("Body"))
         {
             Debug.Log("I hit the body");
             //hit.rigidbody.AddForceAtPosition(directionRay * force, hit.point);
             //hit.collider.SendMessageUpwards("ApplyDamage", damage, SendMessageOptions.DontRequireReceiver);
         }
          //else if(gameObject.CompareTag("HeadCollider"))
         else if(hit.collider.gameObject.name == GameObject.FindWithTag("HeadCollider").gameObject.name)
         {
             Debug.Log("That was a headshot");
         }

 //            //hit.collider.SendMessageUpwards("ApplyDamage", damage, SendMessageOptions.DontRequireReceiver);
 //            Debug.Log("bodyshot");
 //        }
 //        else if(gameObject == gameObject.FindWithTag("HeadCollider"))
 //        {
 //            Debug.Log("That was a headshot");
 //        }
         
     //}
     // if(Physics.Raycast(transform.position, directionRay, hit, range))

         // }
     // }
