(Dayton, Oh.) – A Boone County couple is among those accused in the 2017 murder of an Ohio man.

Robert Caldwell was shot to death in Riverside, Ohio on August 15. On Tuesday, federal prosecutors announced six people have been charged in connection with the Beavercreek man’s death.

The two main suspects are Caldwell’s ex-wife, 33-year-old Tawnney M. Caldwell, of Centerville, Ohio and the alleged gunman, 34-year-old Sterling Roberts, of Spartanburg, South Carolina. They are both charged with murder and could face the death penalty.

“On August 15, Sterling Roberts allegedly used a firearm that he possessed illegally and traveled interstate to stalk and murder Robert Caldwell,” said Benjamin Glassman, U.S. Attorney for the Southern District of Ohio. “It is alleged that Tawnney Caldwell obstructed justice by destroying the contents and data of a cell phone on that same day. ”

Tawnney Caldwell’s parents, James and Chandra Harmon, of Burlington, are also charged. James Harmon, 55, is accused of aiding and abetting Roberts’ illegal gun possession on August 15.

Prosecutors say Tawnney Caldwell and her mother, Chandra, 54, conspired to intimidate and threaten witnesses after the murder in November.

Tawnney Caldwell as well as Roberts’ brothers, Chance P. Deaking, 25, and Christopher C. Roberts, both of Dayton, are also charged with aiding and abetting.

Five of the defendants were arrested on February 28. Sterling Roberts is currently in state custody in South Carolina.

Robert Caldwell’s 14-year-old son Jacob Caldwell has been missing since his father’s death. The FBI is offering a $15,000 reward for information leading to Jacob’s recovery. Contact the Sugarcreek Township Police at 937-310-3200 or the FBI at 513-421-4310.
