A Las Vegas driver has been sentenced to prison after pleading guilty in connection with a fatal hit-and-run crash that killed a pedestrian near the Las Vegas Strip.
Authorities said the driver, operating a BMW SUV at a high rate of speed, struck a man crossing the street before continuing to drive away from the scene. The case later resulted in criminal charges and a prison sentence.

According to the Las Vegas Metropolitan Police Department, the collision happened around 3:30 a.m. on May 30, 2025, near West Flamingo Road and South Las Vegas Boulevard.
Police said 29-year-old Jeffrey Ryan Diedenhofen was crossing West Flamingo Road outside of a marked or implied crosswalk when he was struck by a 2016 BMW X5 driven by 37-year-old Stephon Watkins.

Charges
Following the investigation, Watkins was initially charged with hit-and-run and reckless driving.
Authorities later announced that he was arrested in Sacramento, California, in December and returned to Clark County, Nevada, to face prosecution.
According to court proceedings, Watkins ultimately pleaded guilty to failure to stop at the scene of a crash involving death.

Speed
During sentencing, prosecutors and family members referenced video evidence connected to the crash.
According to statements presented in court, Watkins allegedly accelerated before the collision and reached speeds of approximately 86 mph in a posted 35 mph zone.
The victim’s father, John Diedenhofen, argued that slowing down or braking could have prevented the fatal impact.
He stated in court that, based on the available footage, he believes his son may have survived if the vehicle’s speed had been reduced even slightly.
Traffic safety experts often note that pedestrian survival rates decrease significantly as vehicle speeds increase, especially above urban speed limits.
Statement
While appearing in court for sentencing, Watkins reportedly expressed remorse but said he had been attempting to make a green traffic light at the time of the collision.
His comments were referenced in coverage by the Las Vegas Review-Journal.
Court hearings in fatal crash cases often include victim impact statements from family members alongside remarks from defendants before sentencing decisions are issued.
Officials did not indicate that impairment played a role in the crash.
