Investigators found a an extensive amount of forensic evidence as they reviewed the Times Square SUV and bomb material.The New York Times reports on the failed bomb:

Among the enduring images left by car bombings, overseas or in the United States, is investigators on their hands and knees, crawling through the wreckage searching for clues: a blasting cap or a timing device, a piece of the explosive’s casing or a trace of the chemicals used.

Car bombs, by design, do their best to devour any evidence of their existence, or send it flying.

On Saturday in Times Square, a homemade bomb built inside a Nissan Pathfinder did not explode — and as a result, a trove of evidence was left behind for investigators to pore over, not only for physical evidence or forensic clues, but also as a reflection of an assailant’s methods, mind-set and possible motives.

More information should be forthcoming as the FBI investigates the SUV and related evidence at their lab in Quantico, VA:

And when the bomb in the Pathfinder did not go off, the authorities had not only the vehicle, but also the raft of explosive elements packed inside: two neon-color alarm clocks and the time one was set to, some batteries, two five-gallon gasoline containers, three propane tanks, firecrackers, fertilizer packed in clear plastic bags bearing a store’s logo, a cooking pot and a 78-pound metal gun box, a GC-14P 14-gun steel security cabinet manufactured by Stack-On, the police said.

Moreover, a car is an ideal receptacle for microscopic or invisible traces of who might have been inside. The authorities have been dusting the outside of the Pathfinder for fingerprints. Inside, they can search for traces of hair or skin cells that might have sloughed off on a steering wheel or a seat cover. They may find literature tucked into a glove box, or some food under a seat.

Each clue will be its own mini-investigation, in an inquiry that is involving “hundreds” of officers and agents, said Deputy Commissioner Paul J. Browne, the Police Department’s chief spokesman.

Deborah Blum’s newest book chronicles the history of forensic medicine and two of the early pioneers. The New York Times book review weighs in:

“The Poisoner’s Handbook” is structured like a collection of linked short stories. Each chapter centers on a mysterious death by poison that Norris and Gett­ler investigate, but the reader never gets to know these principals well enough to find out what drives their tireless devotion to scientific inquiry. Instead, Blum lavishes her attention on her chosen villains — the poisons — and their deadly maneuverings through the body. A Pulitzer Prize-winning science writer, she provides the gruesome particulars of autopsies and laboratory work — like the pulverizing of organs and the boiling of bones — and a variety of chemical tests. With descriptive talents and a knack for detail, she introduces us to lively killers. One, carbon monoxide, is a “chemical thug” that works “by muscling oxygen out of the way.”

Deborah Blum shared her ‘Top Ten Poisons‘ during an interview with Amazon.com. The ‘Top 5′ are listed here:

1. Carbon Monoxide (really)–It’s so beautifully simple (just two atoms–one of carbon, one of oxygen) and so amazingly efficient a killer. There’s a story I tell in the book about a murder syndicate trying to kill an amazingly resilient victim. They try everything from serving him poison alcohol to running over him with a car. But in the end, it’s carbon monoxide that does him in.

2. Arsenic–This used to be the murderer’s poison of poisons, so commonly used in the early 19th century that it was nicknamed “the inheritance powder”. It’s also the first poison that forensic scientists really figured out how to detect in a corpse. And it stays in the body for centuries, which is why we keep digging up historic figures like Napoleon or U.S. President Zachary Taylor to check their remains for poison.

3. Radium–I love the fact that this rare radioactive element used to be considered good for your health. It was mixed into medicines, face creams, health drinks in the 1920s. People thought of it like a tiny glowing sun that would give them its power. Boy, were they wrong. The two scientists in my book, Charles Norris and Alexander Gettler, proved in 1928 that the bones of people exposed to radium became radioactive–and stayed that way for years.

4. Nicotine–This was the first plant poison that scientists learned to detect in a human body. Just an incredible case in which a French aristocrat and her husband decided to kill her brother for money. They actually stewed up tobacco leaves in a barn to brew a nicotine potion. And their amateur chemical experiments inspired a very determined professional chemist to hunt them down.

5. Chloroform–Developed for surgical anesthesia in the 19th century, this rapidly became a favorite tool of home invasion robbers. If you read newspapers around the turn of the 20th century, they’re full of accounts of people who answered a knock on the door, only to be knocked out by a chloroform soaked rag. One woman woke up to find her hair shaved off–undoubtedly sold for the lucrative wig trade.
