My son was convicted of murder1 , there was no prints,no dna,no weapon and no one who could put him on the street of the murder. Procicutors got 3 known criminals to help with information after this case sat cold for 2 and 1/2 years. These criminal all made deals on there own cases ,and 1 admitted that he lied to get out of his own trouble. These guys were the only evidence the DA had,and their credibility was bad since they all told different versions of the story. Please explain how does these things happen.
