As the oldest of 3 children and the only daughter, Hanna had a close relationship with her mother.
She called the police, but they were hesitant to investigate a missing adult as no evidence of foul play was brought up.
Authorities also discovered through his phone records that Lankford talked to Hanna from 5:08 pm to 5:36 pm that evening.
In April 2005, Hanna moved out with Lankford.
