Hi Jillian,
This is Josh from the New York State Police. We do not have a green alert here. The alerts we have are Amber, Managed by the NYSP and then we have a missing child alert, Missing/Vulnerable adult alert and missing college student alert that is managed by the Missing Persons Clearinghouse at the Department of Criminal Justice Services (DCJS). These alerts basically have everything covered. I do not forsee NY adding any other alerts in the near future.
Josh
