 The father of a Middle Tennessee teenager found in northern California this week with her former 50-year-old teacher after being missing for nearly six weeks says he thinks his daughter was brainwashed. 
 
 Anthony Thomas, the father of 15-year-old Elizabeth Thomas who was at the center of a more than month-long nationwide Amber Alert, told ABC's Good Morning America on Friday that his daughter will need therapy and that her family plans to get her any help she needs. 
 
 "We're very happy that we're going to see her again," he told GMA. 
 
 Thomas added he hadn't had the opportunity to speak with his daughter yet but plans to talk with her sometime today. 
 
 Meanwhile, the California man who alerted law enforcement and led them to Elizabeth and Tad Cummins — the 50-year-old man accused of kidnapping her told Good Morning America that several clues made him suspicious about them. 
 
 "The girl really wasn't looking at me or anything and he was kind of dominating the conversation," Griffin Barry said on national television Friday morning. 
 
 Barry, 29, said he called 911 after he ran into the pair at a gas station in Cecilville and they told him they needed money for gas and food as well as a place to stay. 
 
 Barry said Cummins told him they had lost everything in a fire in Colorado and needed a place to stay. Cummins told Barry, a caretaker on property that includes a gas station, that their names were John and Joanna. 
 
 Barry told ABC he put gas in their car, gave them cash and put them up in a cabin nearby. 
 
 In the interview with ABC, Barry said he didn't talk to the pair much but he noticed Cummins tried to "keep her away." 
 
 He also said Cummins did all the talking and said they had been at the Black Bear Ranch commune, but left because they didn’t like it. 
 
 "I had a photo of him that was the Amber Alert and I was like, that’s definitely the guy, and then we saw the car as well and it matched up. Then we called the police right after that," Barry told ABC. 
 
 About 9:30 p.m Wednesday Barry called the owner of the cabin and told him he thought the pair were Cummins and Elizabeth.

 The next morning, at 9:30 a.m. the Siskiyou County Sheriff’s Office arrested Cummins at the cabin off Eddy Gulch Road and rescued Elizabeth, according to the sheriff's office and the Tennessee Bureau of Investigation.

 (CNN) In the days before he allegedly abducted his 15-year-old student, Tennessee teacher Tad Cummins refilled a prescription for Cialis, took out a loan for quick cash and made hotel reservations in another state, actions investigators believe show he was planning to leave with the girl. 
 
 Details about those facts and other surprising revelations were found in the criminal complaint against Cummins in the sensational case. 
 
 The car 
 
 On March 13, Cummins told his wife he needed to borrow her Nissan Rogue to go for a job interview at the Williamson County Medical Center. 
 
 "Subsequent investigation revealed that Cummins had no scheduled interview," the complaint said. 
 
 The loan 
 
 Shortly after Cummins disappeared with one of his students, Tennessee authorities discovered that he had falsified information on an application for a $4,500 title loan. 
 
 Cummins' wife told authorities on March 14 that her husband wanted to get the loan "to meet their financial needs during his suspension from work without pay." He was suspended for his interactions at school with the student. Cummins' wife also said the money from the loan, two handguns, clothes and toiletry items were missing after he left. 
 
 The pills 
 
 Cummins had been prescribed Cialis -- a drug used to treat erectile dysfunction, his wife told investigators. He obtained two refills of Cialis before leaving town. 
 
 The one-bed motel-rooms 
 
 Investigators found out that Cummins booked rooms -- in his own name -- at Super 8 motels in Oklahoma City and in Guymon, Oklahoma, in March. Employees at both properties told investigators each room had one bed. 
 
 The purchases 
 
 Cummins and the student visited a Wal-Mart when they were in Oklahoma. In Guymon, Cummins bought women's razors, chocolates, and a "commonly used lubricant for sexual intercourse," according to the complaint. 
 
 Here's the full complaint: 

 The 50-year-old Tennessee teacher arrested for running away with his 15-year-old student prepared for the trip by picking up two refills of his erectile dysfunction medication. 
 
 Tad Cummins expressed relief to officials who collared him Thursday in Cecilville, Calif. — 2,400 miles from his home in Culleoka, Tenn., CNN reported 
 
 "I'm glad it's over," he reportedly told the SWAT team that arrested him. 
 
 Cummins and former student Elizabeth Thomas had been on the run since March 13, and authorities scoured for clues as to where they were headed. 
 
 Tenn. teacher accused of abducting student arrested in California 
 
 A federal complaint filed against the former teacher at Culleoka Unit School revealed Cummins refilled his Cialis prescription and made reservations at Super 8 Motels in Oklahoma City and Guymon for the weekend of March 16. He arranged for the rooms, each of them with a lone bed, under his own name before going on the run. 
 
 Authorities said the actions hinted that he planned to leave with the 15-year-old girl. It’s still unclear if she willingly ran away with her ex-teacher.

 The same day he vanished with Thomas, Cummins told his wife he needed to borrow her Nissan Rogue to go to a job interview at the Williamson County Medical Center. He had been suspended from his teaching job for his interactions with a student and additionally took out a $4,500 loan to meet his "financial needs during his suspension from work without pay." 
 
 He took the loan money as well as a pair of handguns, clothes and toiletry items before he began his weeks-long run with his former student. While they were dodging cops, Cummins also managed to visit a Walmart where he purchased women's razors, chocolates, and a "commonly used lubricant for sexual intercourse," according to the complaint. 
 
 Family pleads for missing teacher who kidnapped girl to return 
 
 Elizabeth is now “en route” to Tennessee where she’ll be reunited with her parents, the family’s attorney told local NBC affiliate WSMV. 
 
 State and federal law officials began moving her back after she underwent medical reviews, he added. 
 
 “We have mental health people that are engaged actively in this case that are going to be working with her for her best interest,” said the attorney Jason Whatley. “We're following their recommendations completely.”

 Cops finally got word of their whereabouts after a Cecilville groundskeeper notified them that the pair had been staying at an unfinished cabin since earlier this week. 
 
 A sheriff’s official at the scene told “Good Morning America” that Elizabeth’s state of mind varied at the scene. 
 
 “She was laughing, she was crying,” he said. “She was kind of an emotional roller coaster as you can imagine.” 
 
 Cummins is due in court Friday, and faces state and federal charges.

 Thomas added his daughter would need therapy, and her family planned to be patient with her. 
 
 Tennessee Bureau of Investigations spokesman Josh DeVine told NBC News’ “Today” Friday morning that Elizabeth appears to be in a healthy physical state. 
 
 The state, he added, will speak with her about what exactly drove the two to disappear. 
 
 “We’re going to be talking with her,” he said. “We want to know exactly what the set of events looked like.”
– Elizabeth Thomas' father says he believes his 15-year-old daughter was brainwashed by Tad Cummins, the former teacher accused of kidnapping her, the Tennessean reports. Cummins and Elizabeth were found this week at a cabin in northern California, weeks after they disappeared from Tennessee. While Anthony Thomas says he hasn't had a chance to speak to his daughter yet—he hopes to soon—he says she is going to need therapy to recover from the ordeal. It remains unclear whether Elizabeth went with Cummins willingly, according to the New York Daily News. Meanwhile, authorities say Cummins' actions prior to going on the lam show he was planning on kidnapping Elizabeth, apparently for sexual purposes. According to a federal complaint, Cummins, 50, refilled his prescription for erectile dysfunction medication and made reservations for one-bed rooms at multiple Super 8 motels prior to kidnapping Elizabeth. CNN reports Cummins told his wife he needed to borrow her car for a (nonexistent) job interview and took out a $4,500 loan "to meet their financial needs." Cummins had been suspended from his teaching job for conduct with Elizabeth. The federal complaint also states Cummins bought chocolates and sexual lubricant at Walmart while on the run with Elizabeth.
