Wanted teen Ethan Couch and his mother may be traveling together in her pickup truck, Tarrant County authorities said Monday at a news conference on the nationwide manhunt. 
 
 Investigators are sifting through “hundreds and hundreds” of leads — including flight, credit card and cell phone records — as they search for Couch, 18, and his mom, Tonya Couch, 48. 
 
 The teen has been wanted since Dec. 11, after he missed his probation meeting, authorities said. Couch’s notorious “affluenza” defense in 2013 spared him jail time for killing four innocent bystanders in a drunk-driving crash. Another victim, a teenager, was left severely brain damaged and paralyzed. 
 
 Former District Judge Jean Boyd sentenced Couch to probation — a “miscarriage of justice” that continues to enrage many in Tarrant County, said Sheriff Dee Anderson. 
 
 “He continues to believe the law doesn’t apply to him, which is how he was raised,” said Anderson, who was visibly angry at a news conference Monday. “If he has enough money, he can get out of it.” 
 
 Anderson said Couch showed no remorse or sympathy the night he killed the victims or afterward. Couch, then 16, who had been drinking at his parents’ second home in Burleson, got behind the wheel with seven people piled into his Ford pickup, authorities said. 
 
 That night, Couch had a blood alcohol content of 0.24 — three times the legal limit for an adult — and was driving 70 mph in a 40-mph zone, authorities said. 
 
 “I said then, we’re not through with Ethan Couch — he’s not the kind of person who rehabilitates, who learns his lesson,” Anderson said. 
 
 Authorities asked for the public’s help in finding Tonya Couch’s Ford pickup truck. It’s a black 2011 Ford F150 Harley Davidson edition with 23 inch chrome wheels and Texas license plate BC50945. There’s damage to the pickup — a “crease” on the passenger side panel. 
 
 Couch’s attorneys, Scott Brown and Reagan Wynn, released a short statement saying they learned that Couch’s probation officer hasn’t been able to reach him or his mother for “the last several days,” prompting the court to call for his detention. The attorneys declined further comment. 
 
 Authorities said they’re not sure the teen and his mom are together, or that she is helping him elude law enforcement. But investigators have a “strong suspicion” that’s the case, Anderson said. Authorities pledged to file criminal charges against anyone proven to have helped Couch elude capture. 
 
 Anderson said he believes Couch decided to go on the run after someone tweeted a video that appeared to show Couch at a beer pong game where there was alcohol. The Twitter user wrote that Couch was violating his probation. His probation terms prohibited him from drinking alcohol, so he wanted to run from the potential jail time he faced, Anderson said.

 Tarrant County District Attorney Sharen Wilson said Couch wasn’t allowed to leave the county without asking permission from his probation officer, which he didn’t do. She declined to say whether his passport had been confiscated. 
 
 Wilson said the victims’ families are being re-traumatized by Couch’s disappearance, and Christmastime makes it even harder. Couch killed 24-year-old Breanna Mitchell, whose SUV had broken down, and three people who had stopped to help: youth pastor Brian Jennings 41, and Hollie Boyles, 52, and her daughter, Shelby Boyles, 21. 
 
 A surviving victim, Sergio Molina, 17, was left severely brain damaged and paralyzed. Another teenage survivor, Soliman Mohmand, suffered broken bones and internal injuries. 
 
 “There isn’t anything more difficult in the world than these people being without their family members and us being focused on the man who killed them,” Wilson said. “It’s just heartbreaking.” 
 
 Couch and his mother lived together by themselves, Anderson said. She was divorced from Couch’s father, Fred Couch, who cooperated with investigators right after Ethan and his mom’s disappearance, telling them he hadn’t heard from either of them in about two weeks. 
 
 Tonya Couch’s mother reported the 48-year-old missing on Sunday. That allowed authorities to enter her name in a national database with a note saying that she is possibly with a fugitive. That way, if police look her up, they will see that information, Anderson said. 
 
 Couch received 10 years’ probation last year in his 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. 
 
 Wilson has filed to move Couch’s case to adult court. If it remains in juvenile court, she said, the maximum he could serve would be four months in detention, until he turns 19 in April. But if the case is moved to adult court, he could face 10 years in prison. 
 
 “Hopefully, we will be able to hold him accountable … and make him pay a price since he hasn’t had to do that so far,” Anderson said. 
 
 In addition to local authorities and the U.S. marshals, the FBI is also assisting with the nationwide search. 
 
 There is a $5,000 reward for information leading to Couch’s capture. Anyone with information about the case may call the U.S. Marshals Service at 800-336-0102. 
 
 The Associated Press and staff writer Claire Cardona contributed reporting. ||||| TARRANT COUNTY, Texas -- Officials released photos Monday of a pickup truck belonging to Tonya Couch, the missing mother of a wanted teen made famous when his lawyer told a Texas court the boy suffered from "affluenza." 
 
 Couch and her son, Ethan, have been missing for more than a week. Ethan Couch, who was 16 years old when he killed four pedestrians in a drunk driving crash, was sentenced in 2013 to 10 years of probation. He is required to check in with a probation officer regularly, but has allegedly been out of contact with authorities for about two weeks. 
 
 Tarrant County Sheriff Dee Anderson said at a press conference Monday morning that authorities believe the mother and son are together, and potentially fled the county in her black 2011 Ford F-150 pick-up.

 "We're trying to account for everything that's possible," Anderson said. "And this pickup truck is one thing we can't account for." 
 
 The truck is a Harley Davidson-themed special edition with 23 inch chrome wheels, and Texas License Plate BC-50945, according to officials. Anderson acknowledged during the press conference that investigators don't know for sure that Tonya and Ethan couch are together. 
 
 "We can't even prove that they're together, we certainly believe that they're together," Anderson said. "If she helped him in any way, we're going to file criminal charges against her." 
 
 U.S. Marshals Service 
 
 Texas sheriff's deputies, U.S. Marshals and the FBI are all searching for the Ethan Couch, whose 2013 sentence cause controversy after his lawyer argued in court that he didn't understand consequences due to his parents' wealth -- a syndrome the lawyer called "affluenza." 
 
 Authorities believe Ethan Couch fled after the Tarrant County District Attorney's Office began investigating a video that surfaced online allegedly showing the teen at a party with several people playing beer pong, a drinking game. 
 
 Tarrant County District Attorney Sharen Wilson said that while her office was looking into the video, it's not why they're now searching for Ethan Couch and his mother. 
 
 "The problem for him on the juvenile probation is that he's not here. Juveniles have to ask for permission to leave the county, and we believe he's not in the county," Wilson said. 
 
 In November, Wilson's office asked a court to move the now 18-year-old's case to adult court, where the potential repercussions for failing to follow the rules of probation are greater. 
 
 "He's looking at possible penitentiary time if he's transferred to adult court," Wilson said, of the potential punishment for Ethan Couch's disappearance. 
 
 Anderson, who is running for reelection in 2016, has conducted a media blitz while searching for Ethan Couch, appearing on national and local television regularly to give updates on the search. On Monday, he said that at the scene of Couch's deadly June 2013 car crash, "those who dealt with him at the accident scene and in the post-accident scene saw no remorse." 
 
 The 16-year-old's blood-alcohol level was three times the legal limit for an adult and there were traces of Valium in his system when he lost control of his pickup truck and plowed into a group of people helping a woman whose car had stalled. 
 
 When he was sentenced six months later to probation, there was widespread outrage in Tarrant County, and Anderson was among many public officials who decried it. 
 
 "Obviously this case is very very important to my agency," Anderson said Monday. "Unfortunately for us, my deputies had to investigate the devastating crime scene ....which resulted from the irresponsible decision that Ethan Couch made."
– "Affluenza teen" Ethan Couch, the Texas 18-year-old who allegedly violated his probation after a drunk-driving crash that killed four bystanders, is still missing along with his mother. They may be traveling in her black 2011 Ford F150 pickup truck, authorities said at a press conference Monday. The Harley Davidson edition truck has 23-inch chrome wheels, a "crease" of damage on the passenger side panel, and Texas license plate BC50945. Per the Dallas News, a "visibly angry" Tarrant County Sheriff Dee Anderson said Couch "continues to believe the law doesn’t apply to him, which is how he was raised. If he has enough money, he can get out of it." He added that investigators have a "strong suspicion" the two are together and Couch's mother is helping him flee the law, though they don't know for sure. Tonya Couch, 48, has now officially been reported missing, CBS News reports. That means she's in a national database for missing persons, and authorities added a note saying she might be with a fugitive, which police will see if they look her up. Anderson said Couch did not appear to have any sympathy after killing the victims: "I said then, we’re not through with Ethan Couch—he’s not the kind of person who rehabilitates, who learns his lesson." Couch missed a probation meeting after a video surfaced that appeared to show him drinking alcohol, and authorities have been looking for him ever since. Anderson said Couch was prohibited from drinking as part of his probation, and likely wanted to escape the jail time he could have faced over the video. Couch's mother is divorced from his father, and authorities say Couch's father has been cooperating with investigators and told them he hadn't heard from his son or his ex, who lived together, in about two weeks. Investigators say they are looking into "hundreds and hundreds" of leads.
