Not reasonably available (as it applies to locating a parent)

Circumstances in which a parent is one whose whereabouts is unknown; who should not be contacted because of the nature of the relationship between the parent and the child; whom there is no way to reach by phone, mail, email, fax or any type of videoconferencing; or who has not responded to multiple contact attempts. “Not reasonably available” does not apply to situations when a parent is at work, traveling, not immediately available by electronic means, or living in another state or country, without more to justify the investigator’s inability to reach the parent and seek parental permission.
