The 15-year-old victim of an ongoing AMBER Alert, and the 50-year-old man she may be with, could "frankly, be anywhere" at this point, the Tennessee Bureau of Investigation said on Thursday.

Elizabeth Thomas, 15, is believed to be with an ex-teacher from her school, Tad Cummins. Authorities say he is armed with two handguns. The pair may be driving a Silver Nissan Rogue with Tennessee tags 976ZPT.

“It’s absolutely important that everyone in this nation know about these individuals because frankly, they could be anywhere right now,” TBI spokesperson Josh Devine said during an update Thursday afternoon.

The two were last seen on Monday morning in Columbia, Tennessee; however, investigators have info placing Thomas in the area of Decatur, Alabama on Monday afternoon.

Since issuing an AMBER Alert Tuesday evening in Tennessee and Alabama, TBI said it has received just 125 tips.

“If 125 leads sounds like a low number, it is. It is the lowest number of leads for an AMBER Alert that we’ve seen go this long. It is alarmingly low,” Devine said. He explained that it indicates the pair may be out of the view of the general public or outside the area across the southeast that have been notified.

On Thursday, TBI issued a second nationwide BOLO so that every agency knows about the alert.

“Law enforcement can not do this alone. We need the public to keep an eye out, pay attention," Devine said.

TBI also revealed Thursday that it has found a troubling pattern of behavior suggesting Cummins may have been abusing his role as a teacher to lure and potentially sexually exploit Thomas.

Cummins, was a teacher at Culleoka Unit School, where Elizabeth went to school.

District Attorney General Brent Cooper have said that Cummins is wanted in connection to an alleged sexual interaction between Cummins and a minor. The school district suspended him when those allegations surfaced and he was fired on Tuesday.

Investigators have put together a timeline placing Cummins and Thomas in the same area just before their disappearance on Monday:

• 7:30 - 7:45 a.m. Monday: A friend of Elizabeth Thomas drops her off at the Shoney's in Columbia, Tenn.

• 8:32 a.m.: Surveillance video appears to show Tad Cummins at a nearby Shell station

• 12:41 p.m.: Maury County Sheriff's Department enters Thomas as 'missing' in NCIC, nation's law enforcement internal communications database

• 3:06 p.m.: Information places Thomas in the area of Decatur, Ala.

Anyone who may have interacted with either Thomas or Cummins before their disappearance should call TBI at 1-800-TBI-FIND.

If you spot the suspect vehicle and can verify the license plate to be TN 976-ZPT, authorities say to call 911.
