According to police, Amanda Thacker, 28, has not been in contact with her family since that time. The last footprint on social media that appears to have been left by her, according to Capt. John Maddox of Onalaska Police Department, was on Dec. 10. It is not believed that Thacker had access to a vehicle.
Thacker's disappearance first was reported by Thacker's mother, who said she hadn't spoken to her daughter in days, which was uncharacteristic of her. When Onalaska police spoke to Thacker's boyfriend, he claimed he found a note from her saying she "needed to be away for a while," said Maddox.
In an effort to follow every possible lead, police have spoken to her friends, family and anyone else who might have information leading to her whereabouts or offer clues to her disappearance.
According to Maddox, Thacker has no history of this type of behavior and no known drug or alcohol issues.
"She was in between jobs. She had gone to Wyoming on a business venture that didn't work out before that," he said, adding that Thacker previously worked for retail and food stores such as Walmart and Brookshire Bros.
Thacker's children are in the care of grandparents in the Dayton area at this time.
When asked if police have developed a list of persons of interest, Maddox said, "Everyone is a person of interest until we get something concrete. We are talking to everybody."
Thacker is described as 5' 4" tall, weighing 160 lbs. with dark hair and brown eyes. Her driver's license lists her hair color as black but it may be dyed a lighter color.
