Emit Particle upon Death

Good Afternoon fellow Devs,

I'm currently working on a Particle System in co-operation with the Ai that emit's a particle upon the enemy's death but just before the body is removed and re-spawned.

I've went ahead and looked for some tips online, however the issue am having here is that the references to gameobject.GetComponent in Unity 5 has changed and suggests I upgrade thus breaking the script.

Is there a better method to do this? Any tips or suggestions are extremely helpful.

My goal for this code is to perform the following functions in C#

1. Player kills AI

2. AI dies

3. A particle emits around the AI upon death

4. The particle stops

5. AI's body is removed from the game

6. Re spawns.

I've got all except number 3 and 4 working, this is where I am having some trouble.

Code:

 public class BloodBath : MonoBehaviour
     {
         //Name of Particle to emit
         ParticleEmitter pe;
 
         private bool isDead = false;
         public float respawnTime = 10.0f;
 
         void Start() {
             ParticleEmitter pe = gameObject.GetComponent<ParticleEmitter> ().particleEmitter;
     }
         
         
         void Update() {
             
             if (isDead)
             {
             
                 //Play Particle upon Death
                 pe.emit = true;
                 
                 respawnTime -= Time.deltaTime;
                 
                 if (respawnTime <= 0.0f)
                 {
                     RemoveBody();
                 }
             }
         }
         
         public void AIDead()
         {
             isDead = true;
         }
         
         void RemoveBody() {
             
             Destroy(gameObject);
         }
         
     }
     
 }
