Role of steroids in shooting police officers during drug investigation

Law enforcement officers came to Cullen Mutrie for a drug investigation. This ma shot five police officers at his home. As a result, the Greenland Police Chief Michael Maloney was killed; other four police officers were wounded. The next morning this cop-killer and a woman were found dead.
It is suspected that this person was utilizing steroids at the time of the shootout. Jane Young, the New Hampshire Associate Attorney General, noticed that toxicology reports were waiting in order to find out whether metabolites of steroids were in the body of this man.
Police confirmed that Cullen Mutrie had had a very muscular physique. He worked at Genetix Fitness in Seabrook. It was reported that he was 6 feet 3 inches tall. Cullen Mutrie weighed 275 pounds. During a raid which took place in July 2010 law enforcement officials found anabolic steroids at his home. The police officer Wayne Young saw them in a coffee table. He said that he had noticed a plastic bag with some vials. A vial was with powder; others contained solution. The labels indicated that they were steroids.
The New Hampshire State Crime Lab analyzed the vials. It was determined that the vials contained such medications, as Trenbolone Acetate, Sustanon 250, Boldenone Undecylenate and Nandrolone Decanoate.
John Miller, a professor of kinesiology, was asked whether a connection between the deadly actions and “roid rage” of anabolic steroids could present. The professor confirmed that it was plausible. But according to him, it is impossible to conclude that there was a direct link between administration of anabolic steroids and the shootout.
John Miller supposed that steroids that were on the black market were provided from legitimate pharmaceutical companies. But he has been mistaken because the majority of steroids that are sold on the black market are produced in underground labs. It is even suggested that Mutrie produced steroids.
Since a connection between criminal actions and steroid use is a controversial question, not only policemen but also media investigates the case linked with Cullen Mutrie.
