UPDATE: Thursday, August 22 11:50 p.m.
Late Thursday night, the Missouri State Highway Patrol confirmed the body has been positively identified as missing 12-year-old, Adriaunna Horton.
A final news briefing will be held at 1:30 p.m. Friday at the Barton County Ambulance Service Headquarters.
The investigation into Horton's death continues. Anyone with information is asked to contact the Barton County Sheriff's Department at (417) 682-5541 or the Missouri State Highway Patrol, Troop D Headquarters at (417) 895-6868.
According to KY3 News, the father of missing Adriaunna Horton says searchers found her body on Wednesday afternoon.
The 12-year-old went missing from a Golden City park near her home on Monday afternoon, where she was playing with friends after the first day of school.
James Horton, Adriaunna's father, told reporters about the discovery of her body around 2:30 p.m. Wednesday. He didn't have any other details.
Sgt. Jason Pace from the Missouri State Highway Patrol said the Horton family was going to Lamar to look at a body. He could not confirm that the body was Adriaunna's.
A man from Lamar is charged with kidnapping her.
34-year-old Bobby D. Bourne Jr. was charged on Tuesday for kidnapping. He is currently being held on a $1 million bond at Barton County Jail.
According to police, Bourne was arrested Monday evening about 90 minutes after Adriaunna's friends said he drove her away from the park. The friends said she left with Bourne because he said he needed her help to find his daughter, with whom Adriaunna had played with in the past. Horton's father said Bourne once worked for him.
Search teams have been looking for Adriaunna since Monday evening. They rode on horseback and four-wheelers, and the highway patrol used dive teams and a helicopter.
This investigation is ongoing. CBS News has advised KRCG there will be a news conference at 4:30pm on the case. We will continue to update this story as new information develops.
