Bianca Piper was almost a Christmas Day baby. She was born to a loving family on December 26, 1991 in Foley, Missouri. It wasn't long before her family and friends nicknamed Bianca "B."

On the evening of March 10, 2005, just after 6 p.m., investigators said Bianca left her home for a walk around the McIntosh Hill Road area. But that evening, she never returned. Reportedly, Bianca's mother Shannon Tanner reported her missing only a short time later. There have been no confirmed sightings of Bianca or any information leading to her ever since. The St. Louis Dispatch previously reported that police suspected that Piper may have been a victim of foul play.

In 2019, Tanner spoke out to Fox 2 News about her daughter's disappearance,“Nobody else can understand. Even your own family members can go through periods when they’re not as understanding, but only someone who is missing or lost a child can understand."

Over the years, authorities have reportedly worked hundreds of leads in this mysterious case. The National Center for Missing and Exploited Children said Bianca has a scar on her abdomen, arms and legs. When she went missing, her ears were pierced and she was wearing a gray Adidas sweatshirt, jeans and white sneakers. Authorities said Bianca may be in need of medical attention. Fox 2 reports she was bipolar and would often take walks to calm herself down.

Bianca stood 5 feet 6 inches tall and weighed around 185 when she went missing. She's a white female with brown hair and brown eyes. The age-enhanced photo shows what she may have looked like at the age of 24. When the photo was created Tanner spoke to the St. Louis Dispatch about the process and how difficult it has been not to see her child grow over the years, “I can’t even explain what kind of a feeling it is, but when you see your daughter grow up and change, it’s something you want to see in person. The last one that we had made, it took me two or three weeks to open the poster. I had to really get up the courage to do it.”
