Scientists show how technique used to find serial killers can be used to hunt down poaching kingpins

Cambodian law enforcement officials received a tip from investigators in the U.S. Department of Homeland Security. At the freight terminal in Phnom Penh, a cargo container — supposedly carrying legally harvested wood from an African country — was unloaded for inspection. The officials pried open large logs and discovered more than a ton of illegal elephant ivory and other animal parts, hidden in paraffin in the hollowed-out wood.

This haul, recovered about five years ago, was just a small fraction of the 500 tons of raw ivory shipped out of Africa each year, destined for illegal markets in China and Southeast Asia.
