Steven Hayden Pollock

Life and career On September 3, 1977, in Tampa, Florida, while the Second International Mycological Congress was ongoing, Pollock and Gary Lincoff discovered a new species of psychoactive mushroom, which they named Psilocybe tampanensis. including the method of cultivation in brown rice that was later demonstrated to produce mushrooms of high psilocybin content. and became the largest magic mushroom vendor in the world within the same year.

As well as selling mushrooms and prescriptions, Pollock planted an acre of cannabis to get the funds he needed for his research. He traveled to the Amazon and Mexico to study psychoactive mushrooms and discovered three species in 1979: Psilocybe armandii, Psilocybe wassoniorum, and Psilocybe schultesii. In 1980, because of his high volume of illegal prescription writing, the state pharmacy board alerted employees about his practice. As a work-around Pollock bought his own pharmacy to supply his customers.

Death On the evening of January 31, 1981, Pollock worked late at his pharmaceutical practice. He spoke to his girlfriend Mitzi over the phone at seven, and told her that he could not meet her for dinner as he was expecting a patient. At half past nine, he received a phone call from fellow mycologist Paul Stamets, but Pollock cut the call short, claiming that some patients had arrived. Mitzi called several more times through the night, but Pollock did not answer. Worried, she went to his office at eleven. The place had been ransacked and Pollock was lying dead in a corner, having been shot in the head.

The police found 1,753 jars of growing psychoactive mushrooms in Pollock's greenhouse. These were dumped and burned by the San Antonio Narcotics Force.

In 1983, detective Anton Michalec gathered evidence against three men whom he suspected of the murder: Ernest Dietzmann and Jerry Baker, who were drug dependents and patients of Pollock's, and Arthur Lenz, a methamphetamine dealer. An informant told Michalec that these men had plotted to rob Pollock of his money, and their fingerprints matched those found at the crime scene. According to the police report, Michalec brought the case to the district attorney Terry McDonald, who refused to prosecute for unknown reasons. In 2013, journalist Hamilton Morris contacted McDonald, who said that the police report was mistaken, and that he had not been the district attorney at that time. Morris tried to discover who had actually been responsible for the refusal to prosecute, but was informed by the Drug Enforcement Administration that any records which might have contained this information had been destroyed.
