After an international hunt led to the capture of “affluenza” teen Ethan Couch and his mother, the dog that went on the road trip with them to Mexico is still missing. 
 
 The SPCA in Puerto Vallarta, where the Couches were found, has posted a lost-dog notice offering: “REWARD $1000 DOG MISSING IN PUERTO VALLARTA.” 
 
 The dog, a half-shepherd half-wolf mix, answers to the name Virgil, according to the online notice. 
 
 According to the Facebook post, the dog was lost near Colombia and Argentina streets — the same intersection where the Jalisco State Prosecutor’s Office said the Couches were apprehended Dec. 28. 
 
 According to public data, the post was written by a relative of Tonya Couch’s. Reached Wednesday, the relative said she was sorry but she was “not allowed to comment on any of that.” 
 
 The Tarrant County District Attorney’s Office and U.S. Marshals Service say they do not know what happened to the dog. Mexico’s foreign ministry and U.S. Embassy also do not know the dog’s whereabouts. 
 
 Rafael Mayorga, a spokesman for the Jalisco fiscal office, said that he had seen and heard reports about the missing dog but that he had no information about its whereabouts. 
 
 “The dog was never in our possession, so I cannot deny or confirm that the dog was there,” he said, adding that his office is looking into the matter. “This is also a mystery to us.” 
 
 Tonya Couch’s attorney, Stephanie Patten, told WFAA-TV (Channel 8) that her client’s two main concerns are for the welfare of her son and the dog. 
 
 The U.S. Marshals Service issued a wanted notice for Ethan Couch after he allegedly failed to check in with his probation officer in December. It’s believed they fled to Mexico in late November after the release of a video that appears to show Ethan Couch at a party where people are drinking and playing beer pong. 
 
 As a condition of his probation, Couch is not allowed to consume alcohol. Couch received 10 years’ probation in his 2013 intoxication manslaughter case after a psychologist testified he suffered from “affluenza” because his family’s wealth and a dysfunctional relationship with his parents left him without a sense of responsibility. 
 
 Four people were killed and two were left with severe injuries. 
 
 His mother was listed as a missing person after he disappeared. She has been charged with hindering apprehension of a criminal, a felony that carries two to 10 years in prison. 
 
 The Couches first checked into the Los Tules resort in Puerto Vallarta, which advertises itself as pet-friendly. A hotel employee suggested they consider moving to a modest neighborhood where their dog would be welcomed. 
 
 The Couches were tracked down after one of them used a cellphone to order a pizza. They were taken into the custody in the December 5th neighborhood where they were staying with the dog in a low-rent building. 
 
 Ethan Couch remains in a detention center in Mexico. 
 
 He put up a legal fight to keep Mexican authorities from extraditing him to the U.S. His mother was deported back to the U.S. last week and is expected to be in the Tarrant County jail by the end of this week. 
 
 If Ethan Couch is eventually returned to Texas, Tarrant County District Attorney Sharen Wilson has said that the harshest penalty he would face would be 120 days in jail. Wilson has filed a motion to transfer the case — and Couch’s probation — from juvenile court to the adult system.

 Anderson would not disclose further details about the plan to return Couch, who waived her right to extradition in a Los Angeles County court on Tuesday. But he said the paperwork has been finalized. 
 
 “Our people will go get her, and that’s all we’re going to say,” Anderson said. 
 
 Couch is accused of helping her son, Ethan Couch, flee to Puerto Vallarta, Mexico, after he missed a juvenile probation appointment. The two were detained by Mexican authorities last week.

 ▪ ETHAN COUCH: A TIMELINE 
 
 On Wednesday, it was less clear when Ethan Couch would return. He remained in a Mexican detention center after taking legal action to delay his deportation to the United States. 
 
 If Ethan Couch agrees to return, he’ll be brought back to Texas by the U.S. Marshals Service, Anderson said. 
 
 “I’m getting more information from reporters down there,” Anderson said. “There’s nothing we can do from here. We’ll be here for whenever he gets here. We’ll get him back eventually. I fully expect him to use every trick in the book.” 
 
 In another recent development, a relative of Tonya Couch is trying to track down what appears to be a Saarloos wolfdog — a female European wolf and a male German shepherd hybrid — named Virgil that is missing in Puerta Vallarta. 
 
 The relative, Misty McWilliams of Burleson, posted a photo of a wolfdog on SPCA Puerto Vallarta’s Facebook page with a note offering a $1,000 reward for Virgil. 
 
 Tonya Couch’s attorney previously told Star-Telegram media partner WFAA that her main concerns were for her son and her dog Virgil. 
 
 McWilliams did not return a call seeking comment Wednesday night. 
 
 Ethan Couch is on probation for driving drunk on June 15, 2013, killing four people and injuring others, including his passengers. His blood alcohol content was 0.24, three times the legal limit. 
 
 Because he was portrayed during his December 2013 trial as an immature teen from a wealthy but dysfunctional family — with a passing reference by a witness to his being a victim of “affluenza” — Ethan Couch’s sentencing became a national news story. 
 
 He was back in the news late last year after a short video posted on Twitter appeared to show him playing beer pong at a party, which would be a violation of his probation. Missing the appointment with a probation officer is also a violation.

 FORT WORTH — Tonya Couch wants to return to Texas. The mother of "affluenza" fugitive Ethan Couch told a judge in Los Angeles Tuesday that she does not want to fight extradition. 
 
 "Are you the Tonya Couch that is wanted by the State of Texas?" the judge asked. 
 
 Tonya Couch stood behind a glass and wood partition, with her attorney standing closer to the judge. 
 
 A lawyer for the "affluenza" teen's mom questions whether she will receive fair treatment in Tarrant County. 
 
 "Do you understand that you are giving up your right to resist extradition to the State of Texas?" he asked. 
 
 "Yes, sir," she replied. 
 
 Outside the courthouse, Tonya Couch's attorney, Stephanie Patten, then raised questions about whether she can receive a fair trial on a charge of hindering apprehension of Ethan Couch, who last month violated his probation on four intoxication manslaughter convictions in 2013 by fleeing to Mexico.

 "Our biggest concern is that this has become less about the law, and whether [Tonya Couch] broke the law, and more about retribution,” Patten said. “They hate Tonya Couch. They hate Ethan Couch. They want retribution. They want vengeance.” 
 
 She said Tonya Couch is in a cinder block isolation cell in Los Angeles, not mixing with other inmates for her own safety. In court on Tuesday, Couch was wearing the same clothes as when she arrested in Mexico in late December. 
 
 Tarrant County Sheriff Dee Anderson said he may send deputies to retrieve Couch by the end of this week. 
 
 "Her two main concerns remain about her son Ethan, and how he is doing in Mexico... and her dog, Virgil,” Stephanie Patten said. 
 
 The dog went missing after Mexican authorities picked up Tonya and Ethan Couch last week. There has been no word on the pet's whereabouts.

 Eighteen-year-old Ethan Couch and his mother, Tonya Couch, were being held at immigration offices in Guadalajara to be returned to the United States aboard a commercial flight to Houston on Wednesday, authorities said. 
 
 A U.S. Marshals Service agent tipped local authorities off Monday to the location of Couch — who was on juvenile probation after killing four people in a 2013 drunken-driving wreck — and his mother, according to a police report issued by the Jalisco state prosecutors' office. Couch disappeared as authorities investigated whether he had violated the terms of his probation. 
 
 During the sentencing phase of Couch's trial, a defense expert argued that his wealthy parents coddled him into a sense of irresponsibility — a condition the expert termed "affluenza." The condition is not recognized as a medical diagnosis by the American Psychiatric Association, and its invocation drew ridicule. 
 
 According to the police report, one of the Couches' telephones had been used to order delivery from Domino's Pizza to a condominium complex in Puerto Vallarta's old town, far from the glitzy resorts of the city's newer section. 
 
 Agents from the prosecutors' office went to the complex, where a tourism operator told them that the people who had occupied the condo were asked to vacate because the owners were coming to stay, the report said. The Couches then moved to an apartment, and the agents set up a surveillance operation in the surrounding streets. 
 
 On Monday evening, two people matching the Couches' description were spotted and intercepted. The police report said they behaved evasively, claimed to be carrying no IDs, gave inconsistent stories about their names and failed to provide proof of their legal migratory status in Mexico. 
 
 They were taken into custody and handed over to immigration officials. 
 
 Tarrant County Sheriff Dee Anderson said Tuesday that the Couches had prepared to be gone a while, even dyeing Couch's blond hair black. 
 
 "They had planned to disappear. They even had something that was almost akin to a going-away party before leaving town," Anderson said. He would not give details about the event, including how many people attended. 
 
 Anderson said Couch and his mother apparently crossed the border in her pickup and drove to Puerto Vallarta. It was not clear whether they had any accomplices. 
 
 No immediate charges were planned for others who may have known about or assisted with the flight plan, Anderson said. He said authorities have no evidence that Couch's father, who owns a sheet metal factory in North Texas, was involved. 
 
 The sheriff has said he believes the two fled in late November after a video surfaced that appears to show Couch at a party where people were drinking. Authorities had begun searching for the pair after Ethan Couch missed a mandatory appointment with his probation officer on Dec. 10. 
 
 If found to be drinking, Couch's probation could be revoked and he could face up to four months in jail. Once returned to Texas, Couch will be held in a Tarrant County facility until a probation violation hearing Jan. 19. 
 
 Tarrant County District Attorney Sharen Wilson said that at the hearing she plans to ask a judge to transfer Ethan Couch's case to adult court. Couch would then face up to 120 days in an adult jail, followed by 10-year probation. If he violates probation, he could face up to 10 years in prison per death, Wilson said. 
 
 If the judge declines to transfer Couch to adult court, Wilson will ask that his probation be revoked, in which case he could be held in a juvenile facility until his sentence expires when he turns 19 next April. 
 
 Anderson said an arrest warrant was being issued for Tonya Couch on charges of hindering an apprehension, a third-degree felony that carries a sentence of two to 10 years in prison. 
 
 Ricardo Ariel Vera, the representative of Mexico's immigration institute in Jalisco state, said the mother and son were being held at immigration offices in Guadalajara and would be returned to the United States aboard a commercial flight to Houston. 
 
 "They are going to be sent back to their country, given that they were in Mexico improperly," Ariel Vera said. "They would have had to enter, for example, as tourists, but they entered without registering." 
 
 He initially said that would happen Tuesday; however, another immigration official who is not allowed to be quoted by name told The Associated Press that there were no seats available on commercial flights and the return would be Wednesday. 
 
 Couch's attorneys, Scott Brown and Reagan Wynn, said they won't comment until they speak with him, which likely won't happen before Couch reaches the U.S. 
 
 Couch was driving drunk and speeding on a road south of Fort Worth in June 2013 when he crashed into a disabled SUV off to the side, killing four people and injuring several others, including passengers in his pickup truck. 
 
 He pleaded guilty to four counts of intoxication manslaughter and two counts of intoxication assault causing serious bodily injury. A judge sentenced him in juvenile court to 10 years' probation and a stint in a rehabilitation center. 
 
 Greg Coontz, a Burleson, Texas, attorney representing the family of one of the victims of the crash, says his clients look forward to seeing the Couches face the consequences of their actions. 
 
 "I can't think of a worse attempt to evade punishment," he said.

– The dog that may be partially responsible for getting Ethan Couch's deportation to the US delayed has gone missing. The "affluenza teen" and his mom, who has been deported, brought their dog with them when they fled to Mexico, and the SPCA in Puerto Vallarta—where Ethan and Tonya Couch were located by authorities—has reposted a Facebook post originally put up by a relative of Tonya Couch's, the Dallas News reports. The post offers a $1,000 reward for the return of the dog, named Virgil, and says he went missing near the intersection where the Couches were detained, per the News. Not much information is available beyond that—the relative won't comment further; a spokesperson for the Jalisco fiscal office in Mexico says the dog "was never in our possession" but that his office is looking into the animal's whereabouts; and the US Marshals Service, the Tarrant County DA's office in Texas, the US Embassy, and Mexico's foreign ministry all claim to have no idea what happened to Virgil. Per the News, he looks like a "large shepherd mix or wolf hybrid"; the Fort Worth Star-Telegram says he "appears to be a Saarloos wolfdog—a female European wolf and a male German shepherd hybrid." At the Tuesday hearing at which Tonya Couch agreed not to fight extradition from California to Texas, her attorney said Couch's "two main concerns" are Ethan, who is still detained in Mexico, "and her dog, Virgil," WFAA reports.
