Steroid-using US marine killed baby

Audrey Allen, an 18-month old girl, was killed by Joshua Allen Kruzik.
The little girl was killed because she cried in the middle of the night. Joshua Allen Kruzik, an US marine, a friend of Audrey Allen’s parents, decided 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 baby, when she cried. But Joshua Allen Kruzik beat the child very cruelly. As a result, the baby got many severe head injuries. The baby died at a local hospital.
David Kohn, the defense attorney for Joshua Allen Kruzik, affirmed that steroids were responsible for the abnormal behavior of his client. It was affirmed that the killer used anabolic steroids. Before the incident he attempted to discontinue using these preparations but he couldn’t do it. David Kohn confirmed that anabolic steroids produced “roid rage” in Joshua Allen Kruzik. He couldn’t not control his behavior and beat the little child. According to the defense attorney, his client was unconscious. Although he claimed that Kruzik was ready to assume the entire responsibility, he added that he was not guilty.
The baby’s parents also confirmed that their friend applied anabolic steroids. The mother of the child confirmed that she possessed syringes at her home. So, she injected Kruzik with steroids, when he came. Several other individuals also claimed that he applied steroids.
It is strange that anabolic steroids are demonized in this case. Are these medications responsible for the crime? Take in consideration that Joshua Allen Kruzik has been drunk, when he has killed the child!
It is unclear whether the judge will accept the steroid excuse.
