When killers are driven by jealousy and desire, their desperation is evident in both the crime and their efforts to avoid detection. But forensic science can reveal even the slightest mistake to solve crimes of passion.
In most homicides, police rely on motive to pursue a murderer.
But when the killer is a strangerÃ¢ï¿½Â¦the crime may go unsolved for years.
It takes a full arsenal of forensic techniquesÃ¢ï¿½Â¦to traceÃ¢ï¿½Â¦ a lethal encounter.
When a victim is gunned down at point-blank range, police often assume that a friend or acquaintance is to blame. After all, it is difficult for a stranger to commit an assault at such close range. Follow investigators as they use clues to track down the most unlikely of killers.
Most victims of multiple murderers are meticulously chosen because of a mutual connection with the killer or because they match an intricate set of criteria that fits the killer's MO. The most frightening cases of murder occur when the killer appears to choose victims at random, without an apparent connection.
There are several things that can suggest murder; jealousy, anger, poisonâ€¦When everyday substances reveal hidden clues that break a homicide case, those substances become the elements of murder.
Sometimes when a death seems to be accidental or the result of a tragic accident, it is up to forensic scientists to reveal the deception lying just below the surface. Watch as law enforcement officials uncover the hidden betrayals that reclassify cases from accidents to homicides.
Sometimes, the cause of death does not match the scene of the crime. When an untraceable poison is used to commit murder, homicide detectives turn to forensic toxicologists to follow a killer's tracks and expose a toxic death.
For some killers, murder can be a profitable business. And the scene of the crime can be both a source for clues, and puzzling questions. When a victim has been targeted for death, investigators must look beyond the obvious to uncover a murder for hire.
