Leeches, horror film staples, medicinal wonders, and now crime fighters. Police cracked the case of a home invasion and safe robbery when they found one of the suspects' blood inside a leech on the floor and matched his dna.

Familial genetic profiling of law enforcement DNA databases has already been used to succesfully establish both guilt and innocence. Legal and moral questions on these expanded techniques abound and are comprehensively explored by a speaker at a recent FBI symposium on the topic. In the author's words, scenarios previously limited to movies like Minority Report are unfolding quietly, before most of us have thought about the consequences. (Via)

She robs, she injects herself with heroin, she flits across borders like a ghost, she seems to kill with almost professional precision, she leaves clues and bodies – and she has no identity. [more inside]

A discovery leads to questions about whether the odds of people sharing genetic profiles are sometimes higher than portrayed. Calling the finding meaningless, the FBI has sought to block such inquiry.

Bobby Dunbar was a four year-old boy that vanished in 1912, while on a fishing trip with his family in a Louisiana swamp. For weeks, searchers combed the area looking for him. The lake where he went missing was dynamited. Alligators were captured and had their bellies slit open to see if the body was inside. Nothing was found except a set of child's footprints leading to an old railroad trestle. Eight months later, the police found Bobby in the company of a drifter with a horse-drawn cart. He protested his innocence but was arrested and charged with kidnapping. Another woman came forward and claimed Bobby was, in fact, her son. But she was an unmarried fieldworker, and her claims were dismissed. The crime became a nationwide media event and the boy was returned to his parents, and their hometown held a parade in his honor. Bobby returned to his life. Ninety-one years later, Bobby Dunbar's granddaughter uncovered the truth.

DNA frees 3 convicts after 17-year incarcerations --Barry Scheck and The Innocence Project have struck again. Thus far, they have used DNA to free 128 wrongly convicted people. Read Frontline's interview with Scheck. Learn about a sister organization, Northwestern's Center on Wrongful Convictions, which has freed nine Illinois men who were once sentenced to death. For those sentenced to time in the can, prison can be a rough place. How can we prevent innocent people from being put to death? Or fates worse than death?

I just discovered the answer to a question I asked here. Apparently, the police can get a DNA sample from a suspect without the suspect's knowledge or consent. The police probably had a warrant, but the article doesn't say.

Strathclyde Police, Scotland, given the right to take DNA samples from anyone arrested. Previously DNA samples were taken only from those suspected of murders, sex attacks or serious assaults.

Sir John Orr, Chief Constable of Strathclyde Police, denied that compulsory testing would infringe people's human rights. He said: "The tests are not invasive, not intrusive and not against civil liberties. The vast majority of people will be asked only to give a simple mouth swab, which can be done in seconds. This is a magnificent tool which will help detect crime and the public should be very pleased."
