Darrick Toel, 38, entered his written plea Tuesday in Woodbury County District Court to charges of vehicular homicide and operating while intoxicated.
According to court documents, Toel was driving approximately 90 mph at about 7:50 p.m. on July 1 in the 7200 block of Old Lakeport Road when he lost control of his Saturn Ion, left the road, partially rolled and struck a tree.
His passenger, Ryan Toel, 37, of Struble, Iowa, was seriously injured and died two days later.
Officers responding to the crash found several cans of Bud Light, some of them open, inside and outside the car at the scene. A blood test taken about an hour after the crash showed Toel's blood-alcohol content was 0.111 percent, above Iowa's legal driving limit of 0.08 percent, court documents said.
While driving at least 80 mph on Old Lakeport Road, Darrick Toel said, according to authorities, he passed a car, saw an oncoming vehicle and veered to the right, skidding off the road and striking the tree.
Under Nebraska law, it is a felony to procure alcohol to a minor if it results in injury or death to any person and was caused by a minor's consumption of the alcohol or impaired condition that resulted from the alcohol.
The sheriff's office said the man was a passenger in a vehicle that struck a southbound tractor. The impact caused the vehicle to roll into the ditch. The deceased was not wearing a seat belt, a police official said.
Investigators believe the car was traveling south when it left the roadway and struck a pole on the east side of the street. The cause of the accident and contributing factors are still under investigation.
According to court documents, the 37-year-old man had alcohol and marijuana in his system at the time he struck the bicyclist at the intersection of Wesley Parkway and Kansas Street. He later told police he was texting at the time of the collision.
The man drove his Chevrolet Silverado pickup truck through a stop sign at 19th and Rebecca streets at about 6:51 p.m. July 26 and collided with another vehicle. The driver of that vehicle died three days later.
Authorities estimated the man was driving approximately 90 mph when he lost control of his Saturn Ion, left the road, partially rolled and struck a tree. His cousin, a passenger in the vehicle, was seriously injured and died two days later.
In a statement read to the court, Ryan Toel's parents said they do not blame Darrick Toel, Ryan's cousin, for their son's death. "This is an accident that could have gone either way. We will forever be family and always be there for you," they said.
