Little girl was killed because she cried

Audrey Allen, an 18-month old baby, was killed by Joshua Allen Kruzik.
The baby was murdered because she cried in the middle of the night. Joshua Allen Kruzik, an US marine, a friend of Audrey Allen’s parents, was invited to spend weekends at their friends’ home. Before he came to their place, he was at a local bar where he consumed much alcohol. He had to care about the little child, when she cried. But Joshua Allen Kruzik beat her too cruelly. As a result, the little child got a lot of severe head injuries. She died at a local hospital.
David Kohn, the defense attorney for Joshua Allen Kruzik, confirmed that steroids were responsible for the aggression of his client. It was said that Joshua Allen Kruzik took anabolic steroids. Before the incident he tried to stop administering these preparations but he couldn’t do it. David Kohn said that anabolic steroids produced “roid rage” in Joshua Allen Kruzik. He couldn’t not control himself and beat the little girl. According to David Kohn, Kruzik was unconscious. However he said that his client was ready to assume the entire responsibility, he added that he was not guilty.
The little child’s parents also said that their friend administered anabolic steroids. The mother of the child said that she possessed syringes at her home. So, she injected Kruzik with steroids, when he came. Several other persons also confirmed that he administered steroids.
It is strange that anabolic steroids are blamed in this case. Are these medicines responsible for the crime? Consider that Joshua Allen Kruzik has been drunk, when he has beat the baby!
It is not clear whether this defense strategy will work.
