Her release comes a day after a judge lowered her bond from $1 million to $75,000.  Wearing an electronic ankle monitor is part of her bond agreement.  Authorities have accused Tonya Couch of helping her son leave the country to avoid a probation hearing that might have led to jail time for him.  Texas prosecutors had charged her with hindering the apprehension of a felon and bond was initially set at $1 million. That happened in December, after she was returned to the United States but while she was still in Los Angeles, in the custody of the L.A. Police Department.  Couch arrived in Texas on Thursday after a Los Angeles judge approved her extradition more than a week after Mexican authorities detained mother and son in a Pacific resort town.  She was arraigned Friday in Fort Worth but did not enter a formal plea. She will plead not guilty, said Stephanie Patten, her attorney.  During Monday's bond hearing, Tarrant County Judge Wayne Salvant lowered her bond and issued several other conditions.  While Couch is out on bond, she must:  Salvant also issued a gag order for lawyers involved in the case, barring them from communicating with the media.  On Friday, Tarrant County Magistrate Judge Matt King ordered Tonya Couch to undergo a mental exam after the court found "reasonable cause" to believe that she suffers from "a mental illness or is a person with a mental retardation," according to court documents.  The judge's order was issued Friday and must be completed within 30 days.  The mental examination will determine whether there is clinical evidence to support the argument that Tonya Couch may be incompetent to stand trial.  Before she and her son fled to Mexico, she withdrew $30,000 from her account and told her husband that he would not see them again, an arrest affidavit stated.  Before he went to Mexico, Ethan Couch was on probation for killing four people in a drunken-driving accident in 2013, when he was 16.  At the time, outrage followed when a judge sentenced him to probation instead of jail time. During the trial, his lawyers cited the now notorious "affluenza" defense, suggesting he was too rich and spoiled to understand the consequences of his actions.  Ethan Couch is still in Mexico, and his return to the United States largely depends on whether he decides to contest his deportation. Last week, a Mexican judge granted the teen a temporary stay, halting deportation proceedings.  On Monday, Mothers Against Drunk Driving started a petition supporting Tarrant County District Attorney Sharen Wilson's decision to ask for Ethan Couch to be moved from the juvenile justice system to the adult criminal system.
