NPCs follow player in a line

Hi, I have a script which instantiates NPCs once the player passes a house. The NPCs is a simple prefab so I created the script below to let the NPC follow the Player, which works good so far, what I would like to do now is to get multiple NPCs to folow the Player in a clean line, (similar to a snake). I guess the best Approach would be something like the first NPCs follows the Player, the second NPC should follow the first NPC and so on. But I have no clue how to set this up.

 var target : Transform; //the enemy's target
 var moveSpeed = 3; //move speed
 var rotationSpeed = 3; //speed of turning
 var range : float=10f;
 var range2 : float=10f;
 var stop : float=0;
 var myTransform : Transform; //current transform data of this enemy
 function Awake()
 {
     myTransform = transform; //cache transform data for easy access/preformance
 }
  
 function Start()
 {
      target = GameObject.FindWithTag("Player").transform; //target the player
  
 }
  
 function Update () {
     //rotate to look at the player
     var distance = Vector3.Distance(myTransform.position, target.position);
     if (distance<=range2 &&  distance>=range){
     myTransform.rotation = Quaternion.Slerp(myTransform.rotation,
     Quaternion.LookRotation(target.position - myTransform.position), rotationSpeed*Time.deltaTime);
     }
  
  
     else if(distance<=range && distance>stop){
  
     //move towards the player
     myTransform.rotation = Quaternion.Slerp(myTransform.rotation,
     Quaternion.LookRotation(target.position - myTransform.position), rotationSpeed*Time.deltaTime);
     myTransform.position += myTransform.forward * moveSpeed * Time.deltaTime;
     }
     else if (distance<=stop) {
     myTransform.rotation = Quaternion.Slerp(myTransform.rotation,
     Quaternion.LookRotation(target.position - myTransform.position), rotationSpeed*Time.deltaTime);
     }
    
 }
