Animation position changes everytime I play the animation

Hello,

I've been trying to create a death animation for an enemy object in my scene.I created an animation on an empty object in which i placed all my child objects like hands and legs.I animated them but now everytime I try to use the animation at a different position the object plays the animation,but not at the current positon.

I made these two screenshots so maybe they could help u to help me.

This is my death script(the one I use to play the animation) :

 var enemy : Transform;
 var ai : Ai;
 var aiDeath : AIDeath;
 
 function Start()
 {
     ai = enemy.GetComponent(Ai);
     aiDeath = enemy.GetComponent(AIDeath);
 }
 
 function OnTriggerEnter(col : Collider)
 {
     if(col.gameObject.tag=="Bullet")
     {
         enemy.animation.Play("HeadShot");
         Destroy (ai);
         Destroy (aiDeath);
     }
 }

Thank you for your time!
