David Berkowitz

David Berkowitz did not have the easiest childhood.  Some may have thought that he was okay and doing well but he was truly about to go insane.  He was born June 1, 1953 to a mother and father who could not love him.  They gave him up for adoption as soon as he was born.  Berkowitz was adopted by a married couple who tried to set up a normal life for him.  But soon they got divorced and David would struggle to make a good name for himself.  His adopted mother passed away leaving only his adopted father.  His father remarried to a lady who did not appreciate Davids company.  His father and step mother left him at the age of 18 to fend for himself.
Berkowitz joined the military for three years before getting honorably discharged.  In the military he had his first sexual experience with a prostitute.  He then moved to a neighborhood that he explained as driving him to make his first murder.  The neighbors dog howled and howled for hours making it impossible for Berkowitz to sleep.  Soon Berkowitz took the dogs howling to mean that demons were telling him to go out and murder women.  He went out one night under demons orders and stabbed two women.  One only 15 lived after being stabbed 6 times.  He committed 6 murders before being caught.  He was caught because he was spotted crying over a parking ticket.  His car was parked near the murder scene of one victim.  Finally after being identified as the only individual with a parking ticket that night; cops showed up and asked one question.  "who are you"  his answer was "sam".  "son of sam" was an alias that he went by during his killings.
Berkowitz is a unique case because he created an allies and reasons behind his murdering. But in a later article Berkowitz claimed he just said those things incase he got caught he could use his demon story to be tried as criminally insane and receive a lessor of a punishment.  However this was not the case when he was determined mentally stable enough to testify, then he later came clean.  He also expressed he became sexually aroused when he committed his acts.
