Sounds like reasonable doubt to me.

"News Center 7 was in court Wednesday when U.S. Assistant Prosecuting Attorney Amy Smith presented opening statements. She argued to the jury Robert Caldwell was a problem for Roberts and Tawney Caldwell and that Roberts was there to “fix the problem.”
“Sterling shot Bobby again, and again and again — standing there over him, he fired more than 12 shots,” Smith said in court.
Roberts’ defense attorney, Don Malarcik, argued Wednesday that Roberts was not the person who killed Robert Caldwell.
“Tawney Caldwell hired, threatened, coerced someone to kill Bobby Caldwell,” Malarcik said. “That person is not Sterling Roberts.”
Malarcik argued that Tawney Caldwell thought Roberts was “either too scared or too stupid to kill” Robert Caldwell and had a backup plan."
