It turns out that there is indeed suspect DNA in the 1982 Chicago Tylenol Murders. It comes from a "smudge" on or in a tampered bottle. Of course it may or may not be from the actual Tylenol Murderer. Suspect James Lewis gave up his DNA several weeks ago - the FBI has now surely seen the preliminary results, and as no indictment has come against Lewis, it would appear his DNA did NOT match the suspect DNA in the Tylenol case. There were Cyanide deaths in 1984 and 1986 when Lewis was in prison as well.
Ted Kaczynski's family home in Lombard, Illinois is within 20 minutes of all the 1982 Chicago area Tylenol tampering sites, at the exact epicenter in fact. And in July 1982 - the possible "test run" for the September Chicago murders - a man named Jay Mitchell was killed by Cyanide tainted Tylenol right by the Wyoming - Montana border.
I am hoping this DNA development spurs the police and FBI to get the DNA testing on Kaczynski done, so that he hopefully can be strongly ruled in (or out) for Tylenol, Zodiac and other crimes. California investigators, on both Zodiac and EAR/ONS, are seeking DNA and other evidence related to Ted K as well.
I have speculated on a possible link between the Zodiac Killer and the Tylenol Murderer.
The Zodiac Killer said in one of his later letters that his future killing would be disguised as "routine robberies, killings of anger, + a few fake accidents, etc,", which fits the Tylenol Murders. At first, many of the 1982 and 1986 Tylenol and Cyanide deaths were thought to be of natural causes, accidental overdoses, suicides or killings by family members. Zodiac was also suspected of killing a woman in Sonoma County, California named Caroline Davis by Strychnine poison, and in perhaps the first ever case of product tampering, the Fall 1969 sickening of a Martinez, California man named Daniel Williams of BUSH Street who drank Arsenic put into a Seven Up soda pop bottle. In 1984 tax auditor Thomas Dresser of Manitowoc, Wisconsin would die after drinking from a Coca - Cola bottle with Cyanide placed in it. An item found in Kaczynski's cabin indicated he may have visited Manitowoc, Wisconsin to obtain a potassium chemical that can be used to make Cyanide and is poisonous.
Zodiac exhibited an interest in "killing from a distance" - threatening both sniper and bomb attacks. Poisoned products would fit this type of killing as well.
Morf informed me that his research found that in the Fall of 1972, someone sent food products filled with Cyanide to persons in the Sacramento area, with a message that if the "killer" responsible for the Vietnam War was re-elected, these Cyanide filled products would be put on store shelves. At this time period, Kaczynski was known to spend most of the cold weather months outside Montana, often in California, and was particularly known to frequent the Northern California area in general and the Sacramento area in particular. So in 1972, just as in 1969, 1982, 1984 and 1986, areas were it is proven or suspected Kaczynski was at experienced Cyanide tampering incidents.
