PORTLAND, Maine (NEWS CENTER) — Tuesday’s Amber Alert was only the second time one has been issued in Maine.

If you were driving along highways or own a cell phone, you may have noticed an alert message flashing on signs or your mobile device alerting you that Lenore Wilson was missing.

This happens for a few very specific reasons.

An Amber Alert is issued if the following criteria are met:

  1. There has to be reasonable belief a child was abducted.
  2. A law enforcement agency has to believe that child is in imminent danger.
  3. There has to be descriptive information about the child and abduction to assist in finding the child.
  4. That child has to be 17-years-old or younger
  5. The child's name and information has to be entered in the National Crime Information Center System.

It's been nearly nine years since Maine has had to issue an Amber Alert.

The last time it happened was back in November 2009. It was for two-year-old Hailey Traynham. She was kidnapped by her father and eventually found safe in New Hampshire.

A review of the Amber Alert process back then found that everything worked correctly. The child was returned safely to her mother.

The Amber Alert system went into effect in Maine in 2002.
