Robert Caldwell was shot multiple times in front of his three children Aug. 15, 2017, while leaving a counseling appointment in Riverside. He died at the scene. The suspected shooter later was identified as Sterling Roberts.
Roberts is scheduled to go to trial Nov. 30.
Tawnney Caldwell, who was dating Roberts at the time of the shooting, was accused of collaborating with Roberts as well as his brothers Chance Deakin and Christopher Roberts, her mother Chandra Harmon and her stepfather James Harmon to plan, kill and cover up Robert Caldwell’s death, according to the U.S. Attorney’s Office.
The Caldwells reportedly had an ongoing disagreement regarding custody of their children.
While Sterling Roberts was in the Montgomery County Jail, Tawnney had at least two conversations with him about killing Robert Caldwell, according to the U.S. Attorney’s Office.
Before Robert Caldwell was killed, Sterling Roberts reportedly attempted to take his life after posing as a customer needing stonework and scheduling a meeting with him in Jamestown in August 2017. While armed with a gun, Roberts allegedly ambushed Caldwell, who was able to flee and call police.
Between the time of the attempted homicide and murder of Robert Caldwell, Sterling Roberts stayed at a relative’s house in Tennessee before Tawnney Caldwell brought him back to Ohio, according to the U.S. Attorney’s Office.
The pair reportedly planned Robert Caldwell’s death together while at her residence and spoke on the phone multiple times before and after the shooting, investigators allege.
