Siete muertes por cianuro y un misterio sin resolver: la trama detrás de los “asesinatos del Tylenol” en Chicago
Un mensaje que se transmitía por altavoz en las calles de los suburbios de Chicago en 1982 alertó a los vecinos. “No tome Tylenol hasta nuevo aviso”, se escuchaba por los parlantes una y otra vez. La advertencia causó desconcierto, ya que era uno de los medicamentos más comunes para tratar la fiebre o el dolor muscular.
Sin embargo, con el correr de los días, se conoció el motivo de la alerta: el 29 de septiembre de ese mismo año, cuatro personas que tuvieron síntomas similares murieron. Después, los análisis de sangre dieron positivo en la intoxicación por cianuro.

El caos se desató después, cuando se constató que las víctimas habían consumido cápsulas de Tylenol. Por eso, las empresas productoras -McNeil Consumer Products y Johnson & Johnson- retiraron el producto del mercado. Pero, antes de ello, otras tres personas murieron en circunstancias parecidas.
Siete muertes
En la mañana del 29 de septiembre, Mary Kellerman, una nena de 12 años de Illinois, les dijo a sus padres que se sentía mal y que no quería ir a la escuela. Poco después de tomar una cápsula de Tylenol para aliviar su dolor, se desmayó en el piso del baño. Murió unos minutos más tarde.
Ese día, en una localidad cercana, Adam Janus, de 27 años, tomó dos pastillas del mismo medicamento, ya que no se había levantado bien y tenía que ir a trabajar. Sin embargo, de un momento a otro se desmayó y empezó a tener convulsiones. Una vez que lo trasladaron a un hospital, murió a pesar del esfuerzo de los médicos.
Luego de la conmoción por la muerte del joven, su familia se reunió en la casa. Esa tarde, Stanley Janus, el hermano de Adam, y su esposa, Theresa, tenían dolor de cabeza, así que tomaron una dosis de Tylenol cada uno. Pocos segundos después, se descompensaron y empezaron a convulsionar.
En los días siguientes, otras tres muertes ocurrieron en misteriosas circunstancias: Mary Reiner, de 27 años, Mary MacFarland, de 31 años, y Paula Prince, de 35 años, fueron las víctimas.

Luego de una inmediata investigación, las autoridades sanitarias descubrieron que las cápsulas de Tylenol habían sido manipuladas y que, en lugar del medicamento, les habían puesto cianuro.
Una pieza fundamental fue el testimonio de una enfermera llamada Helen Jensen, quien fue la persona que se dio cuenta de la conexión entre las víctimas y el consumo del analgésico.
Por este motivo, Johnson & Johnson hizo un retiro masivo del producto y se descartaron al menos 31 millones de frascos. La alerta de no consumir Tylenol se transmitió por televisión nacional, por las autoridades locales y hasta por los mismos vecinos, que se ofrecieron como voluntarios para informar a cada uno de los residentes de sus barrios.
Los sospechosos
En medio del caos y la desesperación, apareció un primer sospechoso. James William Lewis, un hombre de Nueva York que envió una carta a Johnson & Johnson en la que se atribuía la responsabilidad de los envenenamientos.
En el escrito, exigía un millón de dólares a cambio de detener los asesinatos. La policía logró rastrear las huellas digitales en el sobre y lo identificó. Sin embargo, al comprobar que Lewis no estaba en Chicago durante los asesinatos, lo descartaron como autor material.
A pesar de eso, la investigación siguió señalándolo como sospechoso. Fue condenado por intento de extorsión y pasó varios años en prisión. Si bien la pena era de 20 años en un principio, obtuvo la libertad condicional después de cumplir 13.
Incluso, mientras estuvo preso, ofreció su colaboración para esclarecer el caso. “Si fuera por la calle y su casa estuviera en llamas, no es mi problema, pero me detendría e intentaría ayudar”, aseguró en una entrevista con CNN en 1992. James William Lewis es uno de los principales sospechosos en el caso. (Foto: Chicago Sun / Times).
Con el tiempo, tanto él como su esposa entregaron muestras de ADN y huellas digitales al FBI. Lewis siempre negó cualquier participación directa en los envenenamientos. Sin embargo, documentos del Departamento de Justicia sostienen que, pese a la falta de pruebas concluyentes para procesarlo, es el principal sospechoso.
Pero no fue el único bajo la lupa. También fue investigado Roger Arnold, un residente de Chicago que fue señalado por el dueño de un bar. Pero si bien más tarde quedó libre de toda sospecha, la exposición mediática lo llevó a sufrir una crisis nerviosa: en 1983, confundió a un hombre con la persona que lo había acusado y lo asesinó de un disparo.

Otra mujer, Laurie Dann, apareció en el radar de los investigadores luego de cometer una serie de asesinatos en 1988. Sufría trastornos mentales y, aunque fue considerada como posible autora, nunca hubo pruebas que la vincularan con las muertes provocadas por las cápsulas envenenadas.
Hoy, más de cuatro décadas después, el caso sigue abierto y los siete asesinatos siguen siendo un misterio sin resolver.

FIRST ON FOX: A new report is raising concerns about Turkey’s role in the Middle East, arguing that under President Recep Tayyip Erdoğan, the country has moved away from its traditional Western alignment and toward deeper engagement with Islamist movements, including the Muslim Brotherhood.
The Foundation for Defense of Democracies report, led by senior fellow Sinan Ciddi and titled «Islamist Domination of Turkey: A Forward Base for Muslim Brotherhood-Aligned Jihadism,» argues that Turkey has ties to Hamas — the U.S.-designated terrorist group responsible for the Oct. 7 massacre — as well as to the Muslim Brotherhood — an Islamist movement whose affiliates have recently been designated as terrorist organizations by the United States — placing Turkey’s policies under renewed scrutiny as it prepares to host a NATO summit.
Ciddi told Fox News Digital the shift reflects a broader transformation in how Turkey defines threats.
«What we have is Turkey has completely rewritten the rules of how you interpret what a jihadist terrorist entity may be,» Ciddi said. «Erdoğan has reinvented what is interpreted as a terrorist entity … groups such as Hamas or al-Nusra fall into line with his pan-Islamist view of the world.»

Hamas presence draws scrutiny
A central focus of the report is Turkey’s relationship with Hamas, which the United States designates as a terrorist organization, and yet Hamas expanded its presence in Turkey after 2011, establishing offices and networks inside the country.
«From 2011 onward … Hamas used this opportunity inside of Turkey with a friendly government to establish offices, engage in recruitment (and) fundraising,» Ciddi said.
U.S. authorities have taken action against some of those networks. The Treasury Department has designated Hamas-linked individuals and entities operating in Turkey, a point Ciddi said underscores longstanding concerns.
«The United States Treasury has been tracking and designating Hamas-affiliated NGOs and individuals inside of Turkey,» he said.
The report also alleges that some Hamas operatives have been able to travel using Turkish-issued documents and that senior figures have been publicly received by Erdoğan.
Beyond Hamas, the report describes Turkey as a hub for Muslim Brotherhood figures from across the region, including Egypt and Yemen, many of whom relocated there following crackdowns in their home countries.
Across parts of the Arab world, the Muslim Brotherhood has been banned or restricted for years.
Egypt outlawed the movement in 2013, accusing it of inciting unrest and undermining state institutions. Saudi Arabia and the United Arab Emirates later designated it a terrorist organization, describing it as a threat to national stability, while Bahrain adopted a similar stance.
Jordan dissolved its local chapter this year following arrests authorities said were linked to illicit weapons activity.
Some European countries also have taken steps targeting networks linked to the movement.
Austria, for example, has pursued legal action against individuals and organizations it says are connected to Brotherhood-linked activity as part of its counter-extremism policies.
Officials in these countries have argued that the Brotherhood operates through a mix of religious outreach, political activism, charitable organizations and media platforms to influence public opinion and challenge state authority.

Syria policy and sanctions questions
The report also examines Turkey’s role in Syria, where the country backed opposition forces during the civil war, supporting a range of armed factions, including groups that later formed the Syrian National Army.
«The Syrian National Army … was a hodgepodge collection of militias that Turkey directly armed, paid and organized,» he said.
The report links Turkish support to groups such as al-Nusra and Hayat Tahrir al-Sham, raising questions among analysts about whether such ties could expose Turkish officials to potential sanctions under U.S. law.

A balancing act with Washington
Despite these concerns, other analysts say Turkey’s relationship with the United States continues to act as a constraint on its behavior, while the relationship between Donald Trump and Turkish President Recep Tayyip Erdoğan has been characterized by renewed trust, with Trump praising Erdoğan’s role in Gaza diplomacy.
As Trump celebrated the Gaza ceasefire agreement in Sharm el-Sheikh, Egypt in October 2025, he singled out one leader for extraordinary praise — Erdoğan, whose leadership he credited for helping deliver the Gaza ceasefire.
«A guy who’s been a friend of mine for a long time. I don’t know why I like the tough people better than the soft, easy ones,» Trump said about Erdoğan at the Sharm el-Sheikh summit in October 2025. «This gentleman from a place called Turkey is one of the most powerful in the world … He’s a tough cookie — but he’s my friend.»
Hişyar Özsoy, a Turkish politician and academic, described the relationship between Erdoğan and Trump as «transactional,» noting Washington often relies on Turkey for regional coordination.
In a policy webinar hosted by the Jerusalem Institute for Strategy and Security, Turkish academic Hüseyin Bağcı emphasized that Ankara remains closely tied to Washington.
«The Turkish state is not interested in fighting with Israel because the Turkish government has very good relations with (the) United States of America,» he said. «You cannot be good with America and then be in conflict with Israel.»
Bağcı also suggested Turkey has at times limited Islamist actors domestically.
«Today do you hear anything about» the Muslim Brotherhood, he said. «No … because the president said stop.»

NATO ally under pressure
Turkey, a NATO member since 1952, remains a key partner for the United States, providing logistical access, military capabilities and diplomatic reach.
But Ciddi argued Turkey’s current trajectory increasingly diverges from alliance priorities.
«There is an established track record … where Turkey significantly undermines the transatlantic alliance’s core security concerns,» he said.
He pointed to U.S. sanctions on Turkish entities accused of supplying dual-use goods to Russia, as well as Ankara’s broader strategy of maintaining ties with competing powers.
Iran and regional positioning
As far as Turkey’s positioning itself amid tensions with Iran, Ciddi said Turkey is likely to favor a weakened Iranian regime rather than a complete collapse that could produce a more pro-Western government.
«A weakened Iranian regime is Erdoğan’s safest bet,» he said.
Bağcı offered a similar assessment of the rivalry.
«Iran is not an enemy of Turkey, but not necessarily its best friend. Turkey and Iran are two regional competitors,» he said.

Looking ahead
The report recommends potential U.S. policy responses, including sanctions and increased scrutiny of Turkey’s financial system, steps that could reshape relations between Washington and Ankara.
Fox News Digital reached out multiple times to the Turkish government and to the State Department for comment but did not receive a response in time for publication.

President Donald Trump goes before the nation in prime time on Wednesday evening to deliver what the White House says is «an important update» on the war with Iran.
The president’s address comes amid the month-long attacks by the U.S. and Israel on Iran, which polls indicate are unpopular with many Americans, and a surge in gas prices as a direct result of the fighting have triggered a further slide in Trump’s standing in public opinion surveys.
The political implications are clear: The strikes on Iran and the erosion of the president’s approval ratings are warning signs for the GOP as Republicans ramp up to defend their slim House and Senate majorities in this autumn’s midterm elections.
Trump stood at 41% approval and 59% disapproval in the latest Fox News national poll, which was conducted March 20–23. The president’s negative 18-point margin was up from 14 points in the previous Fox News poll, which was conducted Feb. 28–March 2, as the strikes against Iran began.
FOX NEWS LIVE UPDATES ON THE U.S. WAR WITH IRAN
The president’s approval ratings stood in the upper 30s, with his disapproval in the upper 50s to low 60s, in the most recent national surveys from Reuters/Ipsos, AP/NORC, and Quinnipiac University. A CNN poll conducted March 26–30 and released Wednesday indicated Trump had a 35%-64% approval/disapproval rating.
An average of the most recent national surveys gauging the president’s standing puts Trump just above 40%, with his disapproval in the upper 50s.
WHAT THE LATEST FOX NEWS POLL SHOWS ON THE WAR WITH IRAN
While Trump’s base remains extremely supportive of the president and the war, much of the slippage is coming from within the GOP, specifically those who are considered non-MAGA Republicans.
«I do see in the last couple of surveys an edging down…close to a double-digit movement,» veteran Republican pollster Daron Shaw, who helps run the Fox News Poll with Democrat Chris Anderson, said, pointing to declining support for Trump among non-MAGA Republicans.

Fueling Trump’s decline appears to be the surge in gas prices.
The average price of gasoline in the U.S. topped $4 per gallon on Tuesday, according to national averages from AAA and GasBuddy, for the first time in four years.
FOX BUSINESS: GAS PRICES TOP $4 PER GALLON
The military attacks by the U.S. and Israel have resulted in the deaths of Iranian Supreme Leader Ayatollah Ali Khamenei and other top officials, and the decimation of the country’s military.
In response, Iran has targeted energy facilities with missile and drone attacks in a number of Persian Gulf nations. It has also made the Strait of Hormuz nearly impassable to commercial shipping, bringing roughly 20% of the world’s oil supply to a halt and sending global fuel prices sharply higher.

That has only exacerbated Trump’s polling woes when it comes to his performance on the economy, amid public dissatisfaction with high prices and the cost of living.
A spotlight on inflation helped fuel sweeping victories by Trump and Republicans in the 2024 elections, when they won back the White House and Senate and successfully defended their slim House majority.
DEMOCRATS TARGET TRUMP, GOP, OVER SURING GAS PRICES
But a laser focus on affordability by Democrats, amid persistent inflation, has fueled a slew of victories and overperformances in 2025’s off-year elections and in special elections in the more than 14 months since Trump returned to the White House.
According to the Fox News poll, 80% of respondents said they were concerned about gas prices, and 86% concerned about inflation and high prices. And the CNN survey spotlighted that the president’s approval rating for handling the economy sank to 31%, Trump’s lowest level ever in their polling.
The White House says the surge in prices is temporary.
«When Operation Epic Fury is complete, gas prices will plummet back to the multiyear lows American drivers enjoyed before these short-term disruptions,» White House press secretary Karoline Leavitt said in a statement on Tuesday.
Leavitt emphasized that «President Trump remains committed to fully unleashing American energy dominance, lowering costs, and putting more money back in the pockets of hardworking American families.»
OIL HAS SURGED SINCE THE IRAN CONFLICT BEGAN, BUT GAS PRICES MAY NOT BE DONE RISING
The gas price surge is giving Democrats more political ammunition to target the GOP.
«BREAKING: National Gas Prices Skyrocket to $4 Per Gallon,» read the headline from an email Tuesday morning from the Democratic National Committee.
The House Democrats’ campaign committee last week launched digital ads showing prices at the pump rising and an image saying «D.C. Republicans Did That!» Sources say to expect another round of ads on gas prices in the coming weeks.
But Democrats have their own polling problems, as the party’s brand image has cratered to historic lows in a slew of polls over the past year.
Shaw, pointing to the so-called double-haters, voters who disapprove of both Trump and the Democrats, said that group hasn’t «really swung dramatically to the Democrats» as the midterms approach.
Republican Sen. Ted Cruz of Texas emphasized in a recent Fox News Digital interview that, in his opinion, Trump’s «decision to launch this military action is the most consequential decision» of his presidency.
Such perceptions only increase what’s at stake when Trump addresses the nation in prime time.

«The American people want to hear what the off-ramp for the war is and when it will end,» Dan Eberhart, an oil drilling chief executive officer and prominent Republican donor told Fox News Digital.
Eberhart, who is supportive of the president, said: «Trump’s base is with him, but many ordinary Americans feel the war is unnecessary. Tonight is Trump’s opportunity to explain why this war matters to everyday Americans.»
