No Amber Alert Issued For Missing Children

In order for an amber alert to be issued, there must be a reasonable belief that an abduction has occurred. No amber alert was issued in this case, you figure out the rest:

Investigators are continuing their search today, with help from the FBI, for two children who were last seen at a Pasadena apartment complex two days ago.

Police and others persisted through the night in the search for the 7-year-old boy and his 3-year-old sister, but no new leads were uncovered, a Pasadena police spokesman said.

The children's mother pleaded Monday for their return as police scoured the area around the Sandridge Apartment Homes, 4025 Burke Road, with search dogs and helicopters.
