437:, 44-year-old Graham Backhouse was a farmer who was not well received by his community. On two occasions, Graham reported death threats. In 1984, when his wife Margaret went to use Graham's car to run errands, a bomb ignited when she started it, which nearly killed her. Soon after, police responded to a call from the farm, where they found that Graham had shot and killed his next door neighbor, Colin Bedale-Taylor, in the entry hall, claiming self-defense. The cuts and gashes on Graham's face and chest seemed to support this theory, as they matched a penknife in Taylor's hand which had some of Graham's blood on it and Taylor's initials etched into the handle. Taylor's son had died about a year earlier and he somehow blamed Graham for it, and it was apparent Taylor was behind all the attempts on Graham's life as an act of revenge. However, using forensic science, investigators found that Graham had actually manipulated the crime scene, fabricated the death threats, and planted the bomb, all an elaborate plot to kill his wife and benefit from her life insurance. However, when Margaret survived, he knew he would need a scapegoat to keep up the facade, so he used Taylor. Investigators easily discovered that the penknife actually belonged to Graham, and his wounds were self-inflicted. This proved to detectives that Taylor's murder was premeditated. Graham Backhouse was charged with the murder of Colin Bedale-Taylor and the attempted murder of his wife.
681:. A diatom is only found in water, so police began collecting samples from bodies of water in the area. Analysis of diatoms from a nearby creek matched those found on the boy's body and supplied police with the location of the murder. Months later, 35-year-old divorcee Roland Kubler was convicted of sexual assault and the attempted murder of another teenage boy, which brought him to the attention of investigators. Analysis of Kubler's car led to a match of diatoms found on Dario's body, which led to Kubler's arrest and conviction. Kubler was apparently homosexual and was especially attracted to teenagers. A shrine was built at the creek in Dario's memory, and a statue of him was erected on his grave, which symbolized the delicacy and vulnerability of people as youths.
309:. Each accident was caused by a sudden and impenetrable fog, which forced drivers to suddenly brake without concern for those behind them. 30-year-old trucker Craig Tower was caught up in the accident while en route to visit his mother, Mike Bennett's truck was rear ended by a motor home just moments after he got out of it, an elderly woman and her granddaughter were sandwiched between two semis, and Daryl McKeehan and his family were bounced between the cars as if they were inside a giant pinball. Environmental experts and investigators analysed the elements of nature occurring during this unnaturally-thick fog and tried to determine possible water sources that could create so many vapors in the air. They found one particular facility, the Bowater paper mill, near

After careful analysis, however, it was determined that Hofmann was actually the bomber and that the bomb had gone off accidentally while he was moving it into his car. The motive for the killings was that Christensen discovered Hofmann had been forging and selling historical documents. Hofmann's main intention was to kill Christensen to avoid being exposed, and the other bombings were to make it seem as if all three were provoked by the financial scandal, to which Hofmann had no connection. Hofmann was charged with fraud, the murders of Steve Christensen and Kathy Sheets, and the attempted murder of Kathy's husband, Gary Sheets.

that the family found a six-pack of Cokes at the back door the day before Peggy got sick, and had them with dinner that night. However, Tammy only drank diet soda, and had that instead. She also said that a week before then, Pye received a letter threatening to kill the family if they did not leave the state. The three remaining bottles tested positive for thallium, and found to have been doctored to hide the fact they had already been opened. This told the investigators the killer was someone outside the Carr household, and they turned their attention to the next door neighbors,

Christensen's former business partner, killing his wife, 50-year-old Kathy, after she intercepted it. A teenage boy next door had witnessed the package being dropped off about midnight, but could only describe the car the suspect was driving, a tan minivan. Police had difficulty determining the motive for the killings until a third bomb went off, injuring 30-year-old
563:, and, with this new information, detectives re-opened the investigation into Bruce's death. Stella had increased Bruce's life insurance shortly before his death. Investigators then confronted the Nickells' daughter, who confessed she had helped her mother murder her father. Because the death had to be accidental in order to receive the insurance pay out, Stella laced several other bottles, waiting for a second poisoning to occur. Thanks to her daughter's testimony, Stella Nickell was convicted of the murders of both her husband and Susan Snow.
387:. Subsequently, Peggy's son Duane Hibbert and stepson Travis Carr were hospitalized with similar symptoms. Peggy's second husband of only 6 months, Pye Carr, instantly became a suspect when the poison eventually killed his wife. However, investigators had to check if any other members of the Carr family had been exposed. Shockingly, all but one of them tested positive, the ones with the highest levels being Pye, Peggy's daughter Cissy, and Cissy's daughter Casey. The
