Forensic IT applications in Brazil
Kidnapping in Central Brazil
• Worldwide problem.• 10-15% of the victim
are never recover.
Forensic IT applications in Brazil
Forensic Science in Brazil (1979 – 2002)• 1979 a girl was kidnapped.• 1986 a male baby was abducted.• 2002 parents of 1986 missing child and
teenager boy were observed.• Mother of the girl abducted in 1979 to
question in prosecuted woman.
Forensic IT applications in Brazil
• No legal to donate biological sample for investigation.
• Collected from two cigarette tips discarded• Analysis of 19 marker.• Maternity probability in 99.999996%

Forensic science (2004 - present)
DNA Databank• Missing kids program called “Caminho de
Volta”.• 8,000 kids and adolescents missing in Sao
Paulo State per year.• 30,000 missing kids per year in Brazil.
Forensic IT applications in Brazil
DNA databank• Biological identification.• 15 STR markers.• Investigated 561 unrelated(410 females; 151
males).• High and very discriminating
(99.9993%).
Forensic IT applications in Brazil
Advantage of DNA Databank• Data was stored systematically.• Made possible identification from bone.• Families giving opportunity of children’s
come back home.• The STRs frequencies estimation from
brazilian.
Compare IT between Brazil and Thailand
• In Thailand DNA databank almost use in arrest criminal more than kidnapping.
• DNA databank in Thailand there are seperated such as university, ministry.
• Investigation for paternity testing.
