() A Kansas mother believed to have been coerced into traveling to “a religious rehabilitation facility” in Mexico has been found, authorities said.

The Haskell County Sheriff’s Office reported Monday that Martha Unger, 23, was “confirmed safe.” However, no details were released about where Unger was found or the status of her children.

The Kansas Bureau of Investigation issued an endangered persons advisory for Unger and her two daughters, Madilynn Grace Unger, 2, and Haylie Faith Unger, 1. All three were reported missing from their Haskell County home shortly before 7 p.m. Friday.

“Investigators believe they may have been coerced to travel to Mexico to a religious rehabilitation facility with Corney and Elizabeth Klaasen,” the KBI said.

Authorities did not release any additional details about Corney or Elizabeth Klaasen.

The investigation into the circumstances surrounding Unger’s disappearance is ongoing, according to the sheriff’s office.
