How to make it where if objects don't collide your character dies?

I am pretty new to coding and programming so I am having an issue with figuring out just what should I put in this script so that if my character does not collect something they will die. Below is the coding I have for it but the "else" section of it is marked red from "anim.SetTrigger("Collected") = false;". Please help me find just what the right coding should be.

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class Baby : MonoBehaviour
{
private Animator anim;

public bool GameObject { get; private set; }

private void Start()
{
anim = GetComponent<Animator>();

}


private void OnTriggerEnter(Collider other)
{
if (other.tag == "Character")
{
GameManager.Instance.GetBaby();
anim.SetTrigger("Collected");
Destroy(gameObject, 1.5f);
}
else

{
anim.SetTrigger("Collected") = false;
anim.SetTrigger("Death");


}
}
}
