It is difficult to convict a murderer if the body can't be found. But forensic science is finding ways to do it. Devious killers can think up many was to dispose of their victim's remains, but they are often no matches for creative and devoted investigators. A speck of blood, a piece of a fingernail or a strand of hair may now be enough evidence to prove a murder and capture a killer.

Hairs and fibers: The tiniest filament can become a mark of distinction in the most singular and intimate of ways. Investigators have come to rely on forensic evidence as fine as a carpet fiber or as innocent as an eyelash to crack difficult cases.

Forensic botany & geology: Plants help provide oxygen and nutrients for existence. Soil is the fertilizer of life. Yet both can yield clues to the time and location of a person's death. In criminal investigations, a simple seedpod can provide the missing link by placing a suspect at a crime scene. Dirt left on shoes, tires or clothes can pinpoint a crime scene.

Toxicology: While drugs can cure disease and ease pain, they can also be agents of murder. Toxicologists can examine blood and tissue to uncover cases where death is not as natural as it may seem--from slow arsenic poisoning to quick cocaine overdoses.

Tool marking: A tool used to commit a crime can often be the same tool used to solve it. The pattern a machine leaves on an item, the unusual way a tool crimps a wire, and even something as innocuous as the shape of a wood chip can lead to a killer.
