Accused of slamming a semitruck into another parked on the shoulder of Interstate 80 and killing his co-driver in a fiery crash last week, a Kansas City, Missouri, man could face up to 21.5 years in prison and fines.
Adrian Shawn Doolin, 50, was arrested Thursday, according to his court file.
Carbon County Attorney Sarah Chavez Harkins charged him last week with one count of aggravated homicide by vehicle, which is punishable by up to 20 years in prison and up to $10,000 in fines.
Chavez Harkins also charged Doolin with one count each of:
• Operating a commercial vehicle without a commercial driver’s license (CDL), punishable by up to six months in jail and $750 in fines.
• Failing to maintain a single lane (up to $200 in fines).
• Not keeping a driver’s record of duty status (up to six months in jail and $750 in fines).
• Not showing medical certification to operate a commercial vehicle (up to six months in jail and $750 in fines).
The fiery crash between one parked and one moving semitruck at mile marker 274 near Arlington on I-80 headed east happened before 10 a.m. Sept. 18, and led to the death of Ralph Pimentel, 55, according to an evidentiary affidavit by Wyoming Highway Patrol Lt. Caleb Hobbs.
According to the account of an interview Doolin gave Hobbs on scene, Doolin did could not remember his co-driver’s name.

Still Burning
Hobbs got the call at about 10:02 that morning that two trucks had collided and one was on fire. As he approached, he noticed the smoke plume from 6 miles away, wrote Hobbs.
The weather that morning was sunny with dry roads and very low winds, the lieutenant noted.
On scene, Hobbs found one CR England semitruck resting on its passenger side with the trailer breached, and the rear tandem axels broken off and perpendicular to the trailer and the road.
Farther up the road, he saw a Super EGO trailer, mostly perpendicular to the road with the cab completely engulfed in flames, the affidavit says.
The document says that drivers of other vehicles who were on scene told Hobbs that the drivers of both trucks were in a truck parked in the median, and that the co-driver in the Super EGO truck was still inside the burning cab.
The driver of the CR England Truck was identified by his Wisconsin driver’s license as Philip Essel.
The driver of the Super EGO truck identified himself with his Missouri driver’s license as Adrian Shawn Doolin, says the affidavit.
Doolin told Hobbs he was preparing to switch with his co-driver, whom the Carbon County coroner later identified as Pimentel, and that he was going to pull over in front of the CR England truck.
Scene Evidence
Evidence showed that the CR England truck had been parked in the right-hand emergency lane since about 3 a.m. that day, and was parked about 6 inches past the white fog line on the emergency lane side, wrote Hobbs.
Tire tracks in the emergency lane showed that prior to impact, the approaching truck had braked for about 6 feet in the emergency lane before hitting the CR England truck, says the document.
The CR England trailer was peeled on the driver’s side.
Tire tracks form the super Ego truck showed it traveling into the driving lane, crossing the center line and then turning sharply to the right before coming to rest, wrote Hobbs.
“The impact occurred mainly on the passenger side of the Super Ego truck,” the lieutenant continued. “The crash resulted in the death of Mr. Pimentel, who was in the passenger seat of the Super Ego truck at the time of impact. The Super Ego truck then quickly caught fire.”
Six Feet Overlap
The driver of the nearby truck who had given refuge to the two truckers involved told Hobbs that Doolin had mentioned not having a CDL.
Hobbs investigated the matter and found that Hobbs had a Class F — not Class A — Missouri driver’s license, the affidavit says.
Another trooper verified that the Super Ego had hired E-7 Logistics LLC as its company and “did not employ Defendant but did employ Mr. Pimentel,” says the document.
“I had asked the defendant if he knew his co-driver’s name and he could not remember his name,” wrote Hobbs. “I asked if his co-driver could be named Ralph or David, and he stated he could not remember.”
Doolin was life-flighted to Banner Health in Casper, Wyoming, by Intermountain Air Ambulance before Hobbs could ask more questions or issue any citations, says the document.
Hobbs’ affidavit accuses Doolin of showing “gross recklessness by driving a commercial vehicle without a valid operating license.”
Commercial trucks are about 8.5 feet wide. The truck Doolin had been driving verged into the emergency lane by about 6 feet when it crashed, the document alleges.
Doolin had said he saw a truck parked in the emergency lane and was going to switch drivers after passing it, but he hit it in the rear, wrote Hobbs.
“There was approximately a half mile visibility from where the crash occurred and the first sight line to observe the parked CR England truck,” says the document.
Troopers are still investigating the speed of the Super Ego truck. Its actual weight was unknown as of Hobbs writing his affidavit, and it was filled with GOGO applesauce pouches, the affidavit adds.
Hazards
The driver of the CR England truck was cited for parking on a controlled access highway.
His truck had its hazard lights flashing from the cab, but the trailer didn’t have power access so it wasn’t flashing hazards, the affidavit says.
Hobbs added that, “No triangles were behind the CR England vehicle."
The lieutenant wrote that there were no intervening factors like mechanical failure ahead of the crash.
