Cullen Mutrie shot five police officers, when they came to conduct search

Police officers raided the house of Cullen Mutrie for a drug investigation. This ma shot 5 police officers at his home. As a result of the shootout, the Greenland Police Chief Michael Maloney  was killed; four police officers were seriously injured. The next morning Cullen Mutrie and a woman were found dead.
It is suggested 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 person.
Police officials affirmed that Cullen Mutrie had had a very muscular physique. This man worked at Genetix Fitness in Seabrook. It was described that he was 6 feet 3 inches tall. Cullen Mutrie weighed 275 pounds. During a search which was in July 2010 law enforcement officials discovered anabolic steroids at his home. The police officer Wayne Young found them in a coffee table. He said that he had noticed a plastic bag with several vials. One vial was with powder; others contained liquid. The labels indicated that they were steroids.
The vials were analyzed by the New Hampshire State Crime Lab. It was determined that the vials contained such preparations, as Trenbolone Acetate, Sustanon 250, Boldenone Undecylenate and Nandrolone Decanoate.
John Miller, a professor of kinesiology, was asked whether a link between the deadly actions and aggressiveness due to anabolic steroids could present. The specialist affirmed that it was plausible. But according to him, it is impossible to confirm that there was a direct link between administration of anabolic steroids and the crime.
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 which are offered for sales on the black market are manufactured in underground labs. It is even suspected that Mutrie produced steroids.
Since a link between criminal actions and administration of steroids is a controversial question, not only policemen but also media investigates the case related to this killer.
