How can I get the tag of a child object?

My script is sending a raycast message and I wanted my raycast to be able to detect what object it hit. it seems to be able to detect the gameObject with the tag "Body" easily because it isn't a child object, however the component I'm trying to find below that is a child of other child objects so I'm not really sure how to reference it. I know I can use hit.transform.Find("path/etc"), but that doesn't get the tag. Here's my script if it helps.

 void Raycast()
     {
         Ray rayDirection = Camera.main.ScreenPointToRay(new Vector3((Screen.width / 2),(Screen.height / 2)));
         {
             RaycastHit hit;
             {
                 if(Physics.Raycast (rayDirection, out hit))
                 {
                     Distance = hit.distance;
                     {
                         if (animation.IsPlaying ("Fire"))
                         {
                             if (hit.transform.tag == "Body")
                             {
                                 print ("bodyhit");
                                 hit.transform.SendMessage ("Bodyhit", SendMessageOptions.DontRequireReceiver);
                                 Debug.DrawLine(transform.position, hit.point, Color.red);
                             }
 
                             if (hit.transform.GetComponentsInChildren) //I'm not sure what to do here
                             {
                                 Damage += 75;
                                 print ("Headhit");
                                 hit.transform.SendMessage ("Bodyhit", SendMessageOptions.DontRequireReceiver);
                                 Debug.DrawLine(transform.position, hit.point, Color.yellow);
                                 Damage -= 75;
                             }
                         }
                     }
                 }
             }
         }
     }
