Her family and police said she walked from her home, down the road and vanished. "I'm scared because she never did that before," said Debra Neal, Brittney Neal's mother.
Her 22-year-old daughter has apparently not spoken to anyone in nearly two weeks, she said. When Debra Neal last spoke to her daughter on the phone, hours before she disappeared, Brittney Neal had been at home.
Neal said her daughter kept to herself and she knew of no problems or anyone new she may have met online.
The family does not have access to her Facebook account because it doesn't have her password.
"Our leads are diminishing, we need any help we can get," said Jacksonville Sheriff's Office Lt. Rob Schoonover.
JSO confirms it brought cadaver dogs to Neal's neighborhood last week and the park near her home. Police were hoping to find some clue of what happened to her. "No luck, nothing," said Schoonover.
Neal's family continues to call her cell phone and check her bank card. "Her voicemail keeps coming on. What's scaring me is she got a bank card and it hadn't been used," said her mother.
She does not have a history of running off, according to JSO.
"At least let us know you are alright and safe. We want her back no matter what," said Debra Neal.
Her family is passing out flyers around Jacksonville hoping someone has information that can help find her.
Police said Neal was last seen wearing a brown shirt, jean shorts and carrying a brown purse. Police also said she has a tattoo of her name on her right forearm.
