The search for a Hueytown, Alabama woman who disappeared at Panama City Beach almost two weeks ago is now centered in Birmingham. In fact, at least one Bay County sheriff's investigators is in Birmingham tonight, trying to track down the latest on the case.

Pam Biggers walked away from her hotel room at the La Quinta Inn on Thomas Drive while here on business. She hasn't been seen since. Local authorities, along with Biggers’ family launched a massive search for the 52-year-old woman, but turned up nothing.

Friday, Sheriff's Office Chief Investigator Jimmy Stanford was in Birmingham to interview her friends and relatives and check out possible sightings. He says Biggers had mental issues.

Shortly before she disappeared, she and some of her business colleagues were in the beach Walmart. The store's video surveillance system shows Biggers behaving somewhat erratic. Family and friends reported she began hearing voices and carrying on conversations with people who were not there.

Biggers' son is being deployed to Afghanistan, and mental health experts say that could have pushed her over the edge.

Stanford says most likely her mental state probably played a role in her vanishing. But they have not ruled out foul play.

"Someone who is not in their right mind, could have left because they heard something, could have left because they were going to help someone, you know you just don't know even if that's the case. It might have been she got out to take a breath of fresh air and was abducted. We're not eliminating any possibility. We're looking at every avenue in this case."

Friday afternoon Stanford checked out a possible sighting of Biggers at a Birmingham mall several days ago, but it turned out to be a dead end.
