  1. Welcome to Forensics Mr. Rizzo

  2. What is forensics Science? • Use of the scientific method in the legal arena. • The transfer of scientific techniques to aid the legal process. • The use of science and technology to provide evidence.

  3. When is forensics Science used? • ? • To solve any problem whether criminal or historical in nature.

  4. What is Evidence? • Must be relevant to the case at hand. • Must be more probative than prejudicial on the issue. • Probative evidence:tending to prove a particular proposition or to persuade you of the truth of an allegation

  5. Forensic Evidence? • IT IS NOT CSI…. • Is used to establish whether a particular person or thing COULD be at a particular place at a specific time.

  17. Frank Gusenberg handgun problem?

  18. Problem?

  19. Sgt. Thomas J. Loftus • Loftus knew the Gusenbergs real well. • Loftus arrived first at the scene and questioned Frank Gusenberg who was still alive in the garage. • Loftus asked "Do you know me Frank?'   • Frank replied 'Yes, you are Tom Loftus' • Loftus then asks 'Who did it or what happened?' • Frank replies 'I won't talk' • The officer then replies 'You are in bad shape'   • Frank  says 'For God's sake get me to a hospital.' • Loftus tells Frank 'Pete is here too' • He said 'Yes' Loftus asks Frank if they were lined up against the wall, to this Frank answers again 'I won't talk.'

  21. Excerpt from the Follow Up Report • Obvious trauma to his head. There is a Remington m-11 20 gauge shotgun between the victim’s legs with the barrel pointed towards his head and his left hand wrapped around the barrel. The shotgun is inverted with the trigger and magazine trap door pointing up. The barrel end is just above his beltline. There is a sent 20 gauge shell casing on top of a brown corduroy jacket which is on top of a beige nylon shotgun case. These are just to the left of the victim and under one of the stainless steel garden trays.

  28. Suicide Note

  29. Hieronymus Bosch1450-1516 an eccentric Dutch painter of religious visions who dealt in particular with the torments of hell.

  32. Temptation of St Anthony

  33. Temptation of St Anthony(Detail)

  34. Hieronymus BoschMadman or Medical Analyst • So we dig deeper and find that amputated limbs were saved during Bosch's time so they might be rejoined to their owners at the last judgment. • Amputation is a gangrenous prevention • The odd vegetable creature is painted in the shape of a mandrake root. Mandrake was the herb used to stanch the feverish pains of St. Anthony's Fire. • The distillery used to reduce medicinal herbs.

  35. As a Forensic Scientist what are some questions you would ask? • Does he have any diagnosis medical or psychological conditions? • Apocalyptic personality? • What was also happening at that time?

  36. Historians Know: What can be going on at that time? • St. Anthony's Fire was rampant. • fiery pain, hallucinations, disorientation, muscle cramps, convulsions, miscarriages, *gangrene • Today we know that St. Anthony's Fire was caused by a form of Rye/grain fungus called ergot.

  37. St. Anthony’s Fire: Ergot *Ergot of rye is produced by a lower fungus (Claviceps purpurea) that grows parasitically on rye, other grains and wild grasses.

  38. Structural Analysis ergotamine Lysergic Acid

  39. Serotonin Blocker? Serotonin (on the left) and Lysergic Acid ( on the right) *Serotonin is known to control mood, emotion, sleep and appetite

  40. Structural Analysis Lysergic Acid Diethylamide Lysergic Acid (LSD)

  41. Lysergic Acid Diethylamide(LSD) • LSD is one of the most powerful known hallucinogenic drugs. • It was invented in 1938, derived from mushrooms. • SO WHO CARES?

  42. Hieronymus BoschMadman or Medical Analyst • Bosch's Paintings actually documented beliefs and medical procedures used to assist with St. Anthony’s Fire. • Amputation is a gangrenous prevention • odd vegetable creatures= mandrake root • The distillery used to reduce medicinal herbs.

  43. Ergot in history • Furthermore, since ergot baked in bread dough forms LSD, the disease also led to terrifying hallucinations • Indeed there is the belief that the Salem witch-hangings that went on in Salem, Massachusetts (1692) occurred during an outbreak of rye ergot.

  44. Salem Witch trials(June -September of 1692) • 19 men and women were convicted of witchcraft and hung • 100s of others faced accusations of witchcraft. • Dozens languished in jails.  • 1 man was pressed to death under heavy stones

  46. Forensics • from L. forensis "of a forum, place of assembly," from forum. • Used in sense of "pertaining to legal trials," as in forensic medicine (1845).

  47. I. Introduction What is forensics Science? • Use of the scientific method in the legal arena. • The transfer of scientific techniques to aid the legal process. • The use of science and technology to provide evidence.

  48. Is Forensics a Sciences? • Biology • Physiology, Odontology, Pathology • Chemistry • Spectrophotometry, Thin layer Chromatography • Physics • Friction, Ballistics, trajectory and motion • Geology • Archeology, Mineralogy

  49. Evidence? • Must be relevant to the case at hand • Must be more probative than prejudicial on the issue • Probative evidence:tending to prove a particular proposition or to persuade you of the truth of an allegation

  50. History Of Detection • 1879 Alphonse Bertillon: father of Criminal Identification developed Anthropometry • portrait parle • 1892 Francis Galton: the first finger printer • 1910 Edmond Locard: one of the first site based forensic labs • Locard’s Exchange Principle • 1932, the FBI under J.
