According to Ocilla Police Chief Billy Hancock, Ryan Alexander Duke was arrested after being pulled over for speeding on Feb. 20, 2010. According to the police report, an officer said he smelled alcohol on Duke's breath and placed him under arrest.

Duke was allowed to be bonded out to his parents. According to the report, hours later deputies were called to a home where Duke's mother asked for his bond to be released. Duke was then picked up by deputies and taken to Irwin County Detention Center.

Authorities said that until last week, Duke wasn't on their radar in the investigation in Grinstead's disappearance.

While that investigation was still ongoing at the time of Duke's 2010 arrest, authorities said that because it was considered a simple traffic crime and not a serious one, no DNA sample was taken.

In arrest warrants obtained by 11Alive, Duke is accused of entering Grinstead's home, burglarizing it and using his hands to hurt her. The warrants allege he then tried to conceal her death by removing her body from the home.

He's scheduled for a grand jury session on April 12.

11Alive's Ron Jones is working to uncover more about Duke's past and will have full report tonight on 11Alive at Five and 6.
