The Origin of the AMBER Plan

Am erica’s Missing:Broadcast Emergency Response

n Created in 1996q B roadcast of special “alerts” over the airw aves

n Legacy of 9-year-old, Amber Hagermanq Kidnapped and brutally murderedwhile riding her bicycle in Arlington, Texas.

Problem Analysis

n 797,500 children were reported missing;

n 58,200 children were abducted by non-family members;

n 115 children were the victims of long-term non-family abductions called"stereotypical kidnappings“

According to National Incidence Studies of Missing, Abducted, Runaway and Throwaway Children (NISMART)
