Police in Kansas are searching for a mother of three who disappeared as she traveled to Alabama in search of mental health treatment.

Marilane Carter, 36, was last seen leaving her Overland Park home late Saturday. She was driving a gray 2011 GMC Acadia SUV en route to visit family in Birmingham, Alabama, police said in a statement issued Wednesday.

“Ms. Carter has made concerning statements to her family and has not been heard from since later Sunday,” police said, adding that her last telephone contact with relatives put her in the area of Memphis, Tennessee.

Carter’s brother-in-law, Brady McLaughlin, told AL.com that Carter was headed to Alabama in search of mental health counseling and may have contacted the University of Alabama at Birmingham Hospital or Grandview Medical Center to arrange that.

“However she could have chosen to find that help at a place closer to where her phone last pinged,” a Facebook page set up to find the woman reads.

But Carter has not contacted her family, including her husband, who works as a pastor in Overland Park, since late Sunday as she traveled on Interstate 55 entering Memphis.

Carter’s cellphone is dead and no charges have been made to her credit card, McLaughlin said.

“Marilane’s husband and three children, as well as our entire family, just want to know that Marilane is safe,” McLoughlin told the outlet. “The biggest way to help now is to share this story, share any leads or information with law enforcement and pray that God orchestrates a path for her to be found safely.”

The ongoing search for Carter is focused on a 3-mile radius where her cellphone last pinged as she entered Memphis, according to the Facebook page.

“Still no contact with Marilane Carter or her vehicle,” the page reads. “We have received hundreds of messages and tens of thousands of shares. Your prayers and concern is unmatched and we are beyond grateful.”

Carter, who is 5 feet 8 inches tall and weighs 130 pounds, was last seen wearing a green T-shirt and black yoga pants, police said.
