Wade was shot multiple times back in April as he was trying to enforce an eviction notice at a home in Mulhall.
"The family's still very much grieving. I mean they have lots of emotions. I see grief. I see anger. I see exhaustion," said Logan County District Attorney Laura Thomas.
More than a dozen of Wade's family members packed the courtroom Monday, many wearing t-shirts memorializing their loved one.
Many Logan County deputies were there, as well.
"It's something that we deal with every single day that he's no longer here. And, you know, we're forever changed because of that," said Logan County Sheriff Damon Devereaux.
Two of the witnesses testifying Monday were John and Christine Lute.
Wade was enforcing the eviction notice on them when he was shot.
John testified he had just met LeForce the day before when LeForce came to his house to buy a truck from him.
He said they smoked meth together that night and LeForce ended up staying the night in a vehicle outside.
John testified LeForce did not seem angry or agitated or give any warning of what was to come.
"Preliminary's only a very low threshold for the judge to make a determination - can this case move forward? Beyond a reasonable doubt isn't an issue until trial," Thomas said.
The prosecution is seeking the death penalty.
On Monday, they added a fourth aggravator to the bill of particulars; one addressing the Lute's landlord.
"He created a risk of death to more than one person at the homicide scene; that person being the witness, Judy Antle, who was scared she was going to be shot," Thomas said.
Antle also testified on Monday as well as the young lady that LeForce allegedly carjacked after the shooting.
"It's always uncomfortable to look at the man that shot and killed our deputy. It's tough," Devereaux said.
Devereaux has said LeForce is not welcome at his jail.
So, after the judge bound him over for trial, LeForce was transported back to the Payne County jail, where he is being held.
Formal arraignment for LeForce was set for November.
The judge could set a trial date at that time.
Thomas said she anticipates the defense might file a motion for a change of venue but she ultimately thinks the trial will be held in Logan County.
