Case Of Missing Missouri Girl Gets Fresh Look

Police in Lincoln County, Missouri say they're taking a fresh look at the Bianca Piper case, two years after her disappearance. 

After the recovery of Shawn Hornbeck and William "Ben" Ownby, police in the suburban St. Louis area are investigating other missing child cases to see if they may be connected. Police say they're investigating the possible involvement of Michael Devlin, the suspected kidnapper in the Ownby and Hornbeck cases, but don't consider him a suspect at this time.

Bianca is a little girl with a big medical record. Police say the 13-year-old suffered from bipolar disorder, and attention deficit hyperactivity disorder. They say her mood swings would often leave her very angry. Her therapists had always said walking off anger was beneficial for Bianca, and her family often took their doctors' advice, allowing the child to go on walks in her hometown of Foley, Missouri alone.

So police say on March 10, 2005, when Bianca and her mother got into an argument over cleaning up the dinner dishes, Bianca went for a walk. Her mother says she dropped Bianca off about a mile from home with a flashlight, hoping the walk back would calm her daughter. But this time, Bianca did not return home.

Bianca was last seen walking on McIntosh Hill Road wearing blue jeans, white sneakers, and a grey Adidas hooded sweatshirt. Her mental disorders reduce her social capacities to that of a 7-year-old, and require her to take medication daily. Without her medication she becomes incredibly disoriented and could have hallucinations.

The Search Yields No Evidence

Bianca's case captured both national and local attention. The Lincoln County Sheriff's office searched the area around Bianca's home. They were assisted by Eureka Fire Protection District's Equine Search and Rescue Team, Lincoln County Fire and Rescue, St. Charles County Mobile Command, and Helicopters from the Missouri Highway Patrol and Airevac.

The Lincoln County Sheriff's office organized a man-powered search using over 100 men on foot, police dogs, and helicopters to search the hills, woods, and gullies near Bianca's home. Simultaneously the department set up a series of check points for motorists on Bianca's long gravel road. Unfortunately no motorists caught a glimpse of Bianca.

After the local search failed to turn up any evidence of Bianca's whereabouts, investigators broadened the search to include nearby caves, thinking she might retreat to a enclosed area due to Missouri's wintry weather.

Although there have been over 270 miles searched and 15,000 man hours dedicated to finding her, Bianca is still missing. Authorities are still hoping that Bianca has not become the victim of foul play.
