The New Detectives

Psychological Profiling: Journey into the dark recesses and calculated madness present only in our worst nightmares...and in the minds of serial killers. Renowned FBI profiler Robert Ressler can reveal unseen clues about a killer simply by learning details about the crime. From motives to habits, social traits to taste in cards, investigative profiling discloses a killer's hidden motives.

Forensic Photography: Forensic photographers are among the first people at a crime scene, capturing vital clues on film. What do the cameras capture that can't be seen firsthand, and who are the men and women who analyze the camera's clues?

With the advent of DNA analysis, just a few microscopic cells found at a crime scene can be used to put a murderer behind bars. Forensic scientists can analyze droplets of blood, hair fiber, or a piece of chewed gum to determine the identity of a victim or killer or to prove innocence.

Forensic Entomology: Bugs have roamed the Earth for 250 million years, but their intimate association with death is just now coming to light. The kinds of insects on bodies, along with their stage of development, can pinpoint time of death and help identify victims.

Forensic Sculpting: Forensic sculptors retrieve people from oblivion. Using clay and an intricate knowledge of anatomy, forensic arts place a face on an unidentified skull, recreating the victim's likeness, which often leads to his name.

Missing Person: Approximately 1.8 million Americans are reported missing each year. Worldwide, the number of missing persons nearly triples. In addition to pictures on milk cartons, store windows, and in mass mailings, authorities use nationwide computer databases to help locate missing persons or match them with unidentified bodies. Even so, many of the missing are never seen again.

It's difficult to have a murder investigation without a body, and burning up the victim is a time-honored method of destroying physical evidence. But what happens when the charred remains are found, unrecognizable, seemingly impossible to identify? Dr. John Verano and Dr. Doug Owsley of the Smithsonian have faced these challenges, identifying the burned remains of two American journalists found in Guatemala seven years after their reported disappearance.

Fingerprinting: The identification Division of the FBI relies on fingerprints as one of the most effective ways to identify criminals. Fingerprints, along with palmprints and footprints, are an indisputable, time-tested method to establish someone's ID beyond a shadow of a doubt. Computerization has all but eliminated the old inkpad, and print identification that used to take months now takes minutes.

Black Boxes: Little evidence is left after an airplane takes a deadly plunge from the sky. Investigators' best hope for an answer comes from the flight data recorder known as a "black box." Virtually indestructible, the black box could be the only witness to the final horrifying moments of a doomed flight.

Apparent suicide notes, letters from suspected offenders and signatures are scrutinized down to the last dot. Handwriting comparisons can tell if the victim really did sign that new life insurance policy, or if the person who had everything to live for actually wrote the eloquent suicide note.

Orenthal James Simpson was found not guilty of murder. The jury heard hundreds of hours of testimony and every twist and turn of the trial was played out in the media, but what was the evidence? Forensic scientists reconstructed the events that took place on the night Nicole Brown Simpson was murdered. But was their report accurate, and could the evidence be trusted? We'll examine what forensics could and could not tell us about the trial of the century.

Ballistics: A corpse is found with a gunshot wound to the head; the weapon lies next to the victim. It looks like suicide, but could it be murder? It's a question best solved by ballistics experts. Gunshot residues, the pathway of the bullet into the body, shells and the guns themselves all hold important clues. The ability to determine whether an individual has actually fired a gun is vitally important in homicide and suicide investigations.
