What is Computer Forensics and where is it used?
Computer forensics is becoming more and more prevalent in the ever increasing technological age we are living in. Computers and mobile devices have become an integral part of our lives, checking email and sending text messages is now second-nature to most.
This expanded use of computers, mobile phones and pda’s has lead to a large rise in the amount of electronic data that now exists. Social networking sites such as Facebook and Twiiter encourage the sharing of this information with friends in the real world as well as friends who are purely online acquaintances. Often it is the sharing of unauthorised data and where it is being downloaded to that causes issues.
Not all data that is shared over the Internet is completely innocent. Unfortunately the convenience of emails and downlaodable content for the general public also means that it is convenient for criminals.
As an arm of forensic science, computer forensics involves the analysis of electronic data that is stored on a computer or computer network. Computer forensic experts will usually examine such data often as part of a criminal investigation, to find out more details about a particular crime.
Often computer system investigations involve seizing the suspected machines and anlaysing their usage profiles, scanning their hard drives and a multiple of advanced techniques that can restore data that will have been ‘deleted’ by the user.
In recent times computer forensics is known to have been employed effectively to provide intelligence information to help prevent terrorist activities, to identify data theft by employees and to convict criminals who have stored illegal material on their computers.
Conversely, computer forensics can also prove the innoncence of anyone suspected of illegal activity. Like any other branch of forensic science, computer forensic experts will often be able to help make so-called ‘fuzzy’ pictures clearer and by providing a high level of evidence that is accurate and can be relied upon in court.
‘Doe Network’ works to give names to the dead

LIVINGSTON, Tennessee (AP) — Their faces seem to float from Todd Matthews’ computer — morgue photographs, artist sketches, forensic reconstructions — thousands of dead eyes staring from endless Web sites as though crying out for recognition. John and Jane and Baby "Does" whose nameless bodies have never been identified.
His wife, Lori, complains that Matthews, a 37-year-old auto parts supplier, spends more time with the dead than he does with the living, including his two sons, Dillan, 16, and Devin, 6.
You need a hobby, she says, or a goal.
I have a goal, he replies, though he describes it as a "calling."
He wants to give "Does" back their names.
His obsession began two decades ago, when Lori told him about the unidentified young woman wrapped in canvas whose body her father had stumbled on in Georgetown, Kentucky, in 1968. She had reddish-brown hair and a gap-toothed smile. And no one knew her name.
So locals blessed her with one. They buried her under an apple tree with a pink granite tombstone engraved with the words "Tent Girl."
Tent Girl haunted him. Who were her siblings? What was her name?
Matthews began searching library records and police reports, not even sure what he was seeking. He scraped together the money to buy a computer. He started scouring message boards on the nascent Internet.
In the process, Matthews discovered something extraordinary. All over the country, people just like him were gingerly tapping into the new technology, creating a movement — a network of amateur sleuths as curious and impassioned as Matthews.
Today the Doe Network has volunteers and chapters in every state. Bank managers and waitresses, factory workers and farmers, computer technicians and grandmothers, all believing that with enough time and effort, modern technology can solve the mysteries of the missing dead.
Increasingly, they are succeeding.
The unnamed dead are everywhere — buried in unmarked graves, tagged in county morgues, dumped in rivers and under bridges, interred in potter’s fields and all manner of makeshift tombs. There are more than 40,000 unnamed bodies in the U.S., according to national law enforcement reports, and about 100,000 people formally listed as missing.
The premise of the Doe Network is simple. If the correct information — dental records, DNA, police reports, photographs — is properly entered into the right databases, many of the unidentified can be matched with the missing. Law enforcement agencies and medical examiners offices simply don’t have the time or manpower. Using the Internet and other tools, volunteers can do the job.
And so, in the suburbs of Chicago, bank executive Barbara Lamacki spends her nights searching for clues that might identify toddler Johnny "Dupage" Doe, whose body was wrapped in a blue laundry bag and dumped in the woods of rural Dupage County, Illinois, in 2005.
In Kettering, Ohio, Rocky Wells, a 47-year-old manager of a package delivery company, scoots his teenage daughters from the living room computer and scours the Internet for anything that might crack the case of the red-haired Jane Doe found strangled near Route 55 in 1981. "Buckskin Girl," she was called, because of the cowboy-style suede jacket she was wearing when she was found.
And in Penn Hills, Pennsylvania, Nancy Monahan, 54, who creates floor displays for a discount chain, says her "real job" begins in the evening when she returns to her creaky yellow house and her black cat, Maxine, turns on her computer and starts sleuthing.
Monahan’s cases include that of "Beth Doe," a young pregnant woman strangled, shot and dismembered, her remains stuffed into three suitcases and flung off a bridge along Interstate 80 near White Haven in December 1976. And "Homestead Doe," whose mummified body was found in an abandoned railroad tunnel in Pittsburgh in 2000. Her toenails were painted silver.
Monahan was so moved that last year she sought out the tunnel, climbed down the embankment and offered a silent prayer for the young woman whose life ended in such a pitiful place.
"It’s like they become family," Monahan says. "You feel a responsibility to bring them home."
The stories of Doe Network members are as individual as the cases they are trying to solve. Bobby Lingoes got involved through his connection with law enforcement — he’s a civilian dispatcher with the Quincy, Massachusetts, police department. Traycie Sherwood of Richmond, Missouri, joined when her adoptive mother died and she went on line searching for her birth mother. Daphne Owings, a 45-year-old mother of two in Mount Pleasant, South Carolina, needed something to take her mind off the war when her husband was sent to Iraq.
Matches can be triggered by a single detail — a tattoo, a piece of clothing, a broken bone. It’s just a question of the right person spotting the right piece of information and piecing together the puzzle. The process can be tedious and frustrating.
And it can take its toll. Lori Matthews once left her husband for six months because of his obsession with Tent Girl. "He didn’t talk about anything else," she said. "It wasn’t normal."
They reconciled after Matthews agreed to limit the amount of time — and money — he spent on "Does."
Still, Matthews and others say the rewards of cracking a case make the time worthwhile. The Doe Network claims to have assisted in solving more than 40 cases and ruling out hundreds more.
"They do God’s work," says Mark Czworniak, 50, a veteran homicide detective in Chicago.
He first encountered the Doe Network when he was approached by Lamacki, the Chicago bank executive, about potential matches. Unlike some officers, Czworniak has no hesitation about working with civilian volunteers, especially those willing to devote endless hours to cold cases that he cannot get to.
Czworniak says there are hundreds of "Does" in the department files. He is assigned five, including a tall, 30-something man found at the Navy Pier in 2003. Czworniak hopes that the man’s height will help Lamacki or another Network volunteer eventually make an identification.
"She’s like a little bloodhound," says Czworniak, who exchanges e-mails with Lamacki on cases every week and has introduced her to other detectives. "She has the wherewithal and interest and time and she searches these sites I’m not even aware of."
In another sign of the network’s influence, Matthews was asked to serve on a government task force involved in creating the first national online data bank for missing and unidentified.
The National Missing and Unidentified Persons System, NamUS, launched last year, is made up of two databases, one for the missing and one for the unidentified. The goal is to have medical examiners and law enforcement agencies around the country constantly update information on both sites. Next year the sites will be linked and made available for public searching.
No one believes NamUS will put the Doe Network out of business — there will always be a need for people with their expertise to make the necessary connections.
And so, families of the missing will no doubt continue to rely on people like Todd Matthews.
At his house in Livingston, Matthews has built a little nook next to the living room — his "Doe office," he calls it. His desk is laden with pictures of dead bodies. He says he gets many e-mails about cases every week. Every night he scrolls down the lists, searching for new information:
Unidentified White Female. Wore a necklace of silver beads and three small turquoise stones, one resembling a bird. Found in a Calendonia cornfield in New York state in 1979. …
Unidentified White female. Strawberry-blonde hair and 12 infant teeth. Wearing a pink and white dress that buttoned in the back and a disposable diaper. Found Jackson County, Mississippi, 1982. …
Unidentified Black Female. Gunshot wound to the skull. Found next to highway ramp in Campbell County, Tennessee, in 1998…
The last case is close to Matthews’ heart. Sally, he named her, after a Campbell County police officer entrusted him with her skull in 2001.
The police didn’t have the time or means to pay for a clay reconstruction, and so — with the approval of the local coroner — Matthews took the skull to a Doe Network forensic artist. A picture of the reconstructed head was placed on the Network site. The skull sat on Matthews’ desk for over a year, and even Lori, who was at first so horrified she couldn’t look at it, grew fond of Sally. She remains unidentified.
But even Sally cannot take the place of the first Doe, the one who changed Matthews’ life. He still regularly drives to Kentucky, to a lonely plot in Georgetown to visit her.
"She’s family now," he says.
Standing by her grave, he tells of the night in 1998 when, scouring chat rooms for the missing, he stumbled upon a message from Rosemary Westbrook of Benton, Arkansas.
Westbrook sought information about her sister, Bobbie, who was 24 when she went missing 30 years earlier. Bobbie had married a man who worked in a carnival, and she was last seen in Lexington. She had reddish-brown hair and a gap-toothed smile.
Over and over Matthews stared at the message. And in his heart he knew.
Lori, he cried, racing into the bedroom and shaking awake his wife
"I’ve found her. I found Tent Girl."
Weeks later the remains were exhumed. The match was confirmed by DNA.
The family decided to re-inter her in the place that had been her resting spot for so many years. Beneath the stone etched "Tent Girl" they placed a small gray one engraved with her real name, the name that Matthews had restored.
She is Barbara Ann Hackmann, now and for eternity.
