Prosecutors say Cummins planned to cross the U.S. -Mexico border then seek refuge with his 15-year-old former student, Elizabeth Thomas, in Central America.
Cummins was ordered detained as a flight risk and a danger.
The two were finally found when a tip was given to the Tennessee Bureau of Investigation, which followed the lead to northern California.
The former Culleoka Unit School teacher allegedly obtained a "small watercraft and conducted a test run to cross into Mexico across the water from San Diego", ABC News reported.
The Siskiyou County Sheriff's Office responded and found the auto had no license plates, but matched it to Cummins by running the VIN number, the station reports. Authorities said he planned to head to Mexico. The pair disappeared on March 13 and been the subject of an ongoing AMBER Alert before Cummins was arrested and Elizabeth was safely recovered. "It's really hard for her", sister-in-law Danielle Thomas said.
Kimberly Thomas is also barred from coming to their home, the children's schools, or any place the family is reasonably likely to be.

Tensions are still high between the two teams, as Red Sox pitcher Chris Sale almost plunked Manny Machado on Tuesday. He said the Red Sox moved his family away from the scene, and kicked the fan out of the game.
Just days after police rescued Tennessee teen Elizabeth Thomas after more than a month of her disappearance, her father Anthony Thomas filed for divorce from his estranged wife over concerns for the safety of his daughter.
In carrying out his "audacious scheme", the 50-year-old Cummins switched vehicle license plates twice, disabled his vehicle's GPS system, used aliases, altered his appearance, paid only in cash and used back roads during his almost six weeks on the run, according to the documents.
The man who said he helped police capture Tad Cummins, the Tennessee teacher accused of kidnapping a teenaged girl, will receive a $10,000 reward, according to the lawyer for her family. "We'll make sure she'll get what therapy she needs and that she's safe, that she knows she's safe".
He was arrested with her on April 20 in a mountainous, remote area of Siskiyou County, in California, some 68 miles southwest of Yreka. "The criminal complaint details a person who abused a sacred position of public trust as a school teacher so that he could pursue an improper sexual relationship with a juvenile victim who was legally unable to consent to such a relationship", the prosecutors argue.
Kat Bozeman, Elizabeth's sister, has recently given an interview with WKRN regarding her family's ordeal. He was charged for transportation of a minor across state lines for the goal of having criminal sexual intercourse.
Cummins will be shackled and transported from the jail to an airport where he'll board a U.S. Marshal-owned air plane, said Daniel T. Shelton, a spokesman for the U.S. Marshals Service.
