Man at wheel of Lincoln’s fatal O Street Memorial Day crash gets prison time

Kyvell Stark’s attorney Mike Bianchi speaks after the sentencing on Thursday outside Lancaster County Hall of Justice.


Family of two young women killed in a Memorial Day crash in 2022 cried quietly in the back row of the courtroom as Kyvell Stark learned he would go to prison for a decade for driving 90 mph down O Street under the influence of marijuana and smashing into their car.

The collision killed Emily Siebenhor, 20, and Edith Hermosillo, 22, and sent their car and Stark’s into a crowd of onlookers at 52nd Street that had gathered to watch cars cruise that night.

“I would just like to say I was wrong on the decisions that I chose to make at the time,” said Stark, who was 18 at the time of the crash and 20 now.

Kyvell Stark arrives at his sentencing hearing on Thursday for the double fatality crash along O Street in Lincoln on Memorial Day 2022 at Lancaster County District Court.




His attorney, Mike Bianchi, said on May 29, 2022, Stark’s family in Omaha had been out of town on vacation and he took the car and drove under the influence of marijuana, in Stark’s words, “getting a little too caught up in the moment.”

“This is not a bad young man. This is not an evil man,” Bianchi told the judge. “This is a man who’s young, who’s inexperienced, who made a few bad decisions and unfortunately it’s resulted in a terrible tragedy.”

He said Stark, who had no record before pleading guilty to manslaughter and driving under the influence of drugs causing serious injury in this case, still suffers from flashbacks and nightmares.

Bianchi pointed to a letter where Siebenhor’s family said they are not vengeful people “and could not in good heart ask for another adult to be condemned to prison.”

“We’ve all lost loved ones. I’m not sure we’ve lost loved ones the way these people have,” the defense attorney said. “And they have to unfortunately live with that. And my client has to live with the fact that he was wrong.”

Deputy Lancaster County Attorney Ryan Decker spent his time talking about the victims and their families, who are left to deal with “the horror of living every day with this ongoing nightmare.”

“The most important part and the best way to start my comments is to talk about who’s not with us,” he said.

Emily, who was born in Cozad, was studying science communications at the University of Nebraska-Lincoln, where she was in the Cornhusker Marching Band color guard. She loved music, art and animals.

Edith, who was a twin, was born in Lexington, played sports and enjoyed music and acting and was known for her sense of humor.

Decker spoke of Edith’s twin having to tell her parents and siblings of her sister’s death and having to pick out a casket, and Emily’s brother learning of her death at his bachelor party and the empty hole in their hearts. 

“Kyvell Stark took the lives of two young, vibrant, beautiful souls that night. He may have remorse now, but he was not thinking about anyone but himself when he chose to recklessly drive in impaired condition,” Decker said, quoting family.

Decker said this wasn’t an accident.

“Mr. Stark made an intentional choice to smoke marijuana and drive his automobile at an astronomical speed of almost 90 mph during the busiest night of the year on O Street in Lincoln, Nebraska, with thousands of people around,” he said.

In addition to the deaths, 20 people were injured, two seriously.

Lancaster County District Judge Kevin McManaman said “this was completely avoidable.”

“You consumed cannabis, got behind the wheel, you sped down O Street and you just turned your car into a weapon and ended two young lives, two young people who had decades ahead of them,” he said. “And you seriously injured others. And there are no words.”

McManaman said there’s nothing to excuse or justify it, sentencing Stark to 21 to 23 years in prison, near the 23-year max on the charges, and ordering his license revoked for 15 years. With credit for time served and good time, Stark will have to serve roughly nine more years.

Stark’s aunt, who took him in, cried in the hallway as prosecutors spoke with families of the victims.

Down the hall, Bianchi called it “a sad deal all the way around.”

“This ought to be a warning to all these people that want to legalize marijuana,” he said. “You mix this in with some of the other wrong decision-making and these are the disasters that come once in a while.”
