Louisiana police have released a new photo of a woman who disappeared from a religious conference 11 days ago in the hopes it might lead to clues about her whereabouts.

Police still do not know what happened to Mary Byrne "Beth" Smith, 30, of Summerdale, Ala. The kindergarten teacher, mother of two and wife of a Baptist minister disappeared March 24 from Living Proof Live, a women's religious conference held at the CenturyTel Center in Bossier City, La.

Mark Natale, a spokesman for the Bossier City Police Department, released a new photograph of the woman late Tuesday.

On Sunday, around 60 parishioners at the First Baptist Church in Summerdale prayed for the safety of the missing mother, according to a report in the Mobile Press-Register. Her husband did not attend the service.

"We're going to face battles that many of us are not ready for," deacon Jason Richardson was quoted as saying. "Many of us are facing that battle right now. Some of us will hear speculation. We will hear people say things that they have no proof of. We need to be the people that stand with the hand of God."

Smith disappeared the morning of March 24 after telling a female companion that she was going to the concession stand. At the time, evangelist Beth Moore was speaking on the topic of living a life of spiritual victory by growing in one's faith in God.

The conference ended at noon and the friend waited two hours before calling police about Smith's disappearance.

Mary Byrne Smith is described as a 5-foot-3-inch-tall white woman with brown hair and brown eyes. She weighs about 100 pounds and has a tattoo of the sun on her back.

The Smiths have been married 10 years, according to the Press-Register. Mary Byrne Smith is a kindergarten teacher at Elsanor Elementary School in Robertsdale, Ala.

Anyone with information on her whereabouts is asked to call the Bossier City Police Department at 318-741-8605.
