OMAHA — A former Nebraska Medicine surgeon has been sentenced to 10 to 14 years in prison after being convicted of causing a high-speed crash that claimed the life of a 22-year-old woman in midtown Omaha last September.
Mark Carlson, 63, will be eligible for parole after five years and will be mandatorily released after serving seven years, according to Douglas County District Court Judge Duane Dougherty. Carlson, who had no prior criminal record, received credit for 85 days already served.
The sentencing follows Carlson’s February 2025 conviction for manslaughter in the death of Anna Bosma. On September 1, 2023, Carlson was driving his Mercedes AMG at over 100 miles per hour along Dodge Street when he collided with Bosma’s Chevrolet Cruze near the University of Nebraska at Omaha campus at 62nd and Dodge.
Bosma, a recent graduate of South Dakota State University and a new doctoral student in occupational therapy, was visiting Omaha from Sioux Falls, South Dakota, with plans to go to the zoo with her boyfriend.
During Thursday’s sentencing, Carlson offered an emotional apology to Bosma’s family, saying he took full responsibility for what happened. “I will have sorrow, regret and guilt over the loss of Anna for the rest of my life,” Carlson told the courtroom, his voice breaking.
However, Deputy Douglas County Attorney Lindsey Grove pushed back, saying Carlson had failed to take responsibility and that his legal team blamed the crash on a possible medical episode. Grove also said Carlson was involved in a road rage incident at the time and displayed “a clear disregard for human life.”
“This was not just one mistake,” Grove said. “It was a series of reckless decisions that led to the tragic death of Anna Bosma.”
Speaking to reporters after the hearing, Bosma’s parents, Abby and Justin Bosma, said they felt the sentence was fair. “We just wanted to see that justice was done,” said Justin.
