Transform Object over Players head before destroying

Hey Guys,

I want to show the Object the Player collided with over the head of the player before destroying it. It should follow the Player over his head before it gets destroyed. Right now, it looks like this;

     IEnumerator ShowItemOverHead() {
             Destroy(transform.Find("Shadow").gameObject);
             transform.position = new Vector3 (transform.position.x, transform.position.y + 0.7f, transform.position.z);   
             yield return new WaitForSeconds(0.3f);
             GameObject.Destroy (gameObject);
         }

could you help me out with this? Thanks!
