Help my son get his freedom!

My son has been charged with aggrivated attempted murder. When he was first arrested we paid a bondsman 14,000 to get him out. He was out for two yrs never missed a court date he was doing good. The atty he had at the time and the prosecutor decided he needed a 90 day competency evaluation at the State Hospital. It came back that he is competent but now the Judge wont let him out of jail on his bond. The atty he had took himself off the case. He didnt even try to get Jes out of jail before he withdrew.My son os a good person and had no inent on killing anyone. He was trying to protect us. He is being railroaded by the system and a public defender will only hang him

He did nothing to not be able to be back out on his bond. The prosecutor is going with a 16 to life and will not budge. Please help him. What if it were your son? Would you not do anything possible to help him?
