Replace dead npc with ragdoll ?

Anyone know how to add a way to replace my dead NPC with a ragdoll? this is the health script I use in my VR zombie game. Currently it destroys the zombie and it just disappears, ideally I would like for it to make my zombie ragdoll and disappear after a minute

 using UnityEngine;
 using System.Collections;
 
 public class health : MonoBehaviour {
 
    public int actorHealth = 100;
     
     // Update is called once per frame
     void FixedUpdate () {
        if (actorHealth <= 0)
            Destroy(this.gameObject);
     }
 
    public void TakeDamage(int damage)
    {
        actorHealth -= damage;
    }
 
 
 }
