The FBI Files

On October 1, 1993, a stranger abducted 12-year-old Polly Klaas during a slumber party in her home. FBI agents collected fibers from her bedroom and discovered, through the use of laser light sources, a palm print on Polly's bed. After a massive two-month investigation, the FBI arrested Richard Allen Davis. Would the palm prints and fibers match?

In 1982, a California highway patrol officer pulled a young woman over for speeding. He bullied her into sex and then killed her. He then used a decade of police experience to try to cover up his crime and convince investigators of his innocence.

The calm of a Southern Ohio's quiet community was shattered in 1989, when a sniper gunned down an outdoorsman without reason. Hiding in the distance, behind a high powered rifle, a madman was hunting humans along Ohio's county roads.

A young mother and her two daughters were sexually assaulted and brutally murdered in Anchorage, Alaska. With only one piece of forensic DNA evidence, a wash rag carrying pubic lice with which the killer used to clean himself, could the FBI convict their prime suspect, the woman's nephew Kirby Anthoney, on all three counts of murder?

Two couples found themselves on the same deserted island paradise, but only one couple left alive. Buck Walker and Stephanie Sterns arrived in Hawaii on the Sea Wind, which belonged to the missing couple, San Diego millionaires Mac and Muff Graham. This historic case was later depicted in And the Sea Will Tell.

The reputed boss of the Genovese crime family, Vince Gigante wandered the streets of New York wearing only pajamas and a bathrobe, but the FBI was convinced he was anything but crazy.

No suspect had emerged after the rapes and murders of ten women near Tampa, Florida in 1984. The killer was a ruthless and terrifying predator, the newest member of an infamous group known as "serial killers." When one of the killer's victims survived, the FBI was able to identify 31-year-old Bobby Joe Long as the suspect.

In 1989, residents of a close-knit apartment community in Virginia gathered for a holiday celebration. For Tammy Brannen and five-year-old daughter Melissa, Christmas was always a special time. Then, without warning, the little girl was gone.

He was a recluse who spread terror through the mail for 18 years, but Ted Kaczynski wasn't known as the Unabomber until his brother tipped off the FBI. Kaczynski's Manifesto, published in major newspapers, set off a flurry of activity for the FBI: writing analysis and comparisons, DNA gleaned from a single postage stamp and finally, Kaczynski's arrest at his tiny cabin.

A loner and distrustful of authority, Claude Dallas lived off the land, poaching wildlife and selling the hides. When two game wardens confronted Dallas about his deeds, they were shot and killed. After a massive manhunt, Dallas was captured and convicted but escaped months later. On the FBI's Ten Most Wanted list, Dallas eluded agents for nearly year until the FBI tracked him down in California.

On February 26, 1993, an explosion rocked the World Trade Center parking garage. Six people died and more than a thousand were injured in the bomb blast which tore a 5-story crater in the building. Mohammed Salameh, Nidal Ayyad, Mahmud Abouhalima, Ahmad Ajaj, Ramzi Yousef and Eyad Ismoil were convicted and will spend the rest of their lives in prison.

By December 1985, John Gotti (aka the Teflon Don) had assumed his place as the new Don of the Gambino crime family in New York with the assassination of his boss, Paul Castellano. When the FBI convinced Gotti's underboss, Salvatore Gravano, to testify against him, the jury came back with their verdict: guilty on all counts, including the murder of Castellano.

On June 21, 1964, three civil rights workers who set out to educate southern blacks about receiving the right to vote disappeared in Mississippi. After they were found lynched in the rural deep South, the FBI gained the trust of an informant whose information led to the conviction of seven local Ku Klux Klan members. This case was later depicted in the film Mississippi Burning.
