KOLR 10 News obtained the documents Tuesday by the Missouri Department of Social Service's Children's Division.
Craig Wood faces first-degree murder, child kidnapping and armed criminal action in Owens' Feb. 18 death. Her body was found in the basement of his Stanford Street home.
Many of the details in the 37-pages of documents are redacted, including any further information about why investigators believe Owens was sexually assaulted.
The documents call Owens a "victim of circumstance." Investigators said they believe the sexual assault and the killing were both committed in Wood's home, according to the records.
It was not immediately clear what impact the information released by Social Services could have on Wood, since he was not charged with sexual assault. A full autopsy report has not yet been made public in the case.
David Ransin, an attorney representing the girl's parents, said it is a difficult time for family members, who are trying to cope with the information surrounding the case.
"Things are moving forward. Prosecutors and defense attorneys are filing motions and doing their jobs. We need to wait for all the facts to come out before we jump to conclusions," Ransin said. "We need to be patient for the family and the community."
A motions in hearing in the case against Wood will be held at the Greene County Courthouse at 10 a.m. on Wednesday.
