Two men were sentenced to 3 1/2 years each in prison Wednesday for assaulting an epileptic teen, dragging him down the street as they drove off, and then running over his head.

The defendants’ attitudes at the sentencing hearing were juxtaposed, with one contrite and one so cavalier that he was admonished by the judge.

Colby Adam Gilleland, 20, was driving the pickup that struck 17-year-old David Thomas Dopp in front of his west Redmond home on June 3. Despite suffering critical injuries, David has nearly recovered and is doing surprisingly well, said his mother, Becky Dopp.

Gilleland spoke to David’s family at Wednesday’s hearing and said that he never should have gone to their home the night David was hurt.

”I feel horrible for David,” he said. ”I do not believe that this should have happened. I do not. And I just had to tell you guys that it just kills me to see what is happening.”

In contrast, Gilleland’s passenger that night, 23-year-old Trevor Allen Knapp, sat in front of his sentencing judge smirking and rolling his eyes.

”I don’t think you realize the impact you have on people,” said Deschutes County Circuit Court Presiding Judge Michael Sullivan. ”You’ve changed someone’s life forever regardless of what you think your role is.”

After the two men were sentenced, Gilleland’s mother, Leslie Gilleland, embraced David’s mother, and the two women wept.

”When she hugged me, I didn’t know who she was, and she said, ‘I’m Colby’s mom,’” Becky said. ”She asked for our forgiveness.”

Leslie Gilleland also told Dopp that her son had spent a great deal of time wishing he could call or write David to see how he was doing.

Gilleland, of Redmond, pleaded guilty last month to one count each of of felony unlawful use of a weapon and third-degree assault as well as two counts of misdemeanor menacing. Knapp, of Terrebonne, also pleaded guilty to one count each of third-degree assault and menacing.

In an unrelated incident, Knapp also was sentenced Wednesday for drunken driving.

Both men were ordered to undergo a substance abuse evaluation and attend anger control counseling. They will be on supervised parole for three years after their release.

The assault on David happened after a family night out at the Madras Speedway, said Deschutes County Deputy District Attorney Kandy Gies.

After the races, David received a series of threatening cell phone calls while the family went to dinner and then drove home, Gies said. The callers were challenging him to a fight at the Redmond Fred Meyer or at a park.

The calls were coming from Knapp’s cell phone, Gies said.

Gilleland was home at the time, she said, but Knapp got him to meet up at Fred Meyer.

Just as the Dopps arrived home, Becky said, two men in a white pickup pulled up.

Gilleland jumped out of the truck, waving a gun and threatening people, according to Gies. He then got back into the pickup as David Dopp went around to the passenger’s side.

Defense attorneys dispute what happened next, but Gies said Knapp grabbed David and held onto him as the two drove away.

Bend defense attorney Roger Dehoog, who represents Knapp, said that David grabbed his client, not the other way around.

Either way, Gies said David was dragged about 150 feet before he dropped to the pavement and the pickup’s back wheel rolled over his head.

Becky Dopp and her husband, Tom, witnessed the assault and watched as David was run over.

”Me and my husband are left with the memory of that night, seeing him in the street, the truck raising up over his head,” Becky said to the judge. ”We’ll never, ever forget that.”

After the assault, David was flown to St. Charles Medical Center-Bend where he underwent two brain surgeries, one immediately after his arrival.

He spent three days in a medically induced coma in the critical care unit and about two weeks in the hospital, Becky Dopp said.

David’s neurosurgeon said at the time that the teen would likely have died if he hadn’t had surgery within hours after the incident.

David now takes medication for an increase in the number of seizures he has had since the accident, Becky Dopp said. He also struggles with managing his anger about the incident.

”He has a lot of anger and frustration about what we went through as a family, and I think that’s the hardest thing for him,” she said.

David’s hospital bills are now more than $235,000 and continued treatment will cost even more, according to Becky Dopp.

Her family will have to pay about $20,000 because they are not fully covered by insurance, she said.

While the Dopp family is not satisfied that the sentences were long enough, they did not want to go through the strain of a trial, Becky Dopp said.

But she believes that Gilleland’s remorse is real.

”It’s too bad, Colby was put in a bad position and made a wrong choice that night,” she said. I really think he knows he was in the wrong and is genuinely sorry but now it is too late.”
