Police officers, why is he not in jail and how can i get him there?

Get a no trespass order against him being on your mother's property and call the police every time he comes there. Contact his probation officer by calling the local agency where he is being supervised and tell them what he is doing. It may seem like his officer is doing nothing but they have to prove to the judge that he is doing wrong. The judges have problems revoking a probation for technical violations (failure to report, money). Also his officer cannot just take your word for his violations but they will take it into consideration at his next appointment. His probation officer must have proof or see him doing these things (such as driving or being out of the state or more than one dirty UA). In most states, he will be revoked for several things: he gets a new felony charge, he absconds, or it is the end of his probation and he has not completed the terms and conditions of his probation). He got 90 days because the DA could keep him off the streets and away from you for that length of time. Probation would only be for 6 -12 months. The main reason he is not in jail awaiting trial on this new case of fraud is probably because he had someone post his bond.
