Disabling Mouse Look on FirstPerson Controler

I am working on a GUI that at the end of the level will show the players score, but one problem is the character still looks around. I need help.

Script: C#

using UnityEngine;
using System.Collections;

public class LevelChange : MonoBehaviour {

	public string loadLevel;

	void OnTriggerEnter(Collider other) {
			Time.timeScale = 0;

		//Application.LoadLevel (loadLevel);
            //Ignore These comments. This is working.
	}
	
}

Set a reference to MouseLook in normal way, use .enabled = false.

The part that had me stumped for a bit was why such a simple thing did not work at first. After some searching, this explained it

I moved my script to disable the MouseLook into StandardAssets folder and things worked.
