Genealogists can track down criminals

Dick Eastman provides an interesting look at how genealogy can help find criminals in New Zealand.

Christchurch, New Zealand police are targeting the ten families with the most prolific offenders - and have taken the unusual step of preparing family trees to help keep track of all the family members. By knowing who is related to whom, police are able to identify possible suspects much more quickly than by regular investigative means.
It seems that the ten criminal families have cost New Zealand taxpayers $53 million to bring them to justice.
