SAN ANTONIO -

The family of missing woman Leanne Bearden posted on their Facebook that evidence leads them to believe she may have voluntarily left the area of Garden Ridge.

A local private investigator reviewed several text, email, and voicemail messages over the last three months and said there is a strong possibility that Bearden was not happy being back in the United States after travelling the world for two years.

Leanne Bearden has been missing for the past 12 days. She was last seen leaving her in-law's house in Garden Ridge for what she said was to be a one hour walk. She has not been seen or heard from by her family. After an extensive air and land search of a 23 square-mile area including Garden Ridge and the immediate surrounding area, no evidence was found of her presence.

Private investigator Charlie Parker said he won't stop looking until she's found.

“We're searching every aspect and still interviewing people. We're interviewing any lead that we get, and we're keeping track of it. The Garden Ridge Police Department is working with us, and they're ... not giving up," said Parker.

Unfortunately, no one can say if she is still in the state or not. There were reports that she may have been in Houston, but police have determined that was not her. They also do a daily check on her credit cards and bank accounts, and so far no activity has been found.

Anyone with information on the whereabouts of Leanne Bearden, is asked to call Garden Ridge Police at 210-651-6441.

The family posted the following statement on Facebook:

"As you know, Leanne Bearden was last seen leaving her in-law's house in Garden Ridge, Texas, on the afternoon of January 17, 2014 for what she had said was to be a one-hour walk. She has not been seen or heard from by her family since. We initially believed that she was somewhere in the local area. However, after much searching, culminating on January 25 with an extensive air and land search of a 23-square-mile area, including Garden Ridge and the immediate surrounding area, no evidence has been found of her presence.

"The Garden Ridge Police, Comal County Sheriff's office, the Texas Rangers, and other agencies as well as a private investigator have conducted an extensive investigation including talking with many of Leanne’s family members and friends as well as many other people living in this area. They also examined Leanne’s computer and telephone, including emails, text messages, and phone records and contacts. The pressure of transitioning from her two-year trip back into what we consider "normal" life seems to have left her very anxious and stressed. As a result of this investigation, there is evidence that Leanne may have voluntarily left the area, and we understand this is a strong possibility.

"If Leanne has indeed fled this area, she is extremely vulnerable. She left with only a few assets and is traveling very light. Although she is athletic, she is small in stature. Her mental and physical status is uncertain. We fear for her greatly. We urge anyone who might have any information about Leanne to contact the Garden Ridge Police department at 210-651-6441 or Private Investigator Charles Parker at 210-826-4052.

"Please remember Leanne, the Bearden and Hecht families, and all of Leanne's friends in your thoughts and prayers."
