Frank Carr faces sentencing after Interstate 70 crash injured St. Louis Officer Nathan Spiess

Sentencing scheduled in case tied to officer’s amputation

A St. Louis man is set to be sentenced Tuesday in a case stemming from a traffic crash that seriously injured a St. Louis Metropolitan Police Department officer and led to a partial leg amputation. The defendant, Frank Carr, is expected to appear for a hearing that begins at 9 a.m.

The case centers on an incident on Interstate 70 last spring in which Officer Nathan Spiess was struck during events connected to a police encounter. Authorities have said the collision resulted in Spiess losing part of his leg.

Charges and plea: leaving the scene and evidence tampering

Carr pleaded guilty last fall to three felonies: two counts of leaving the scene of an accident involving injuries and one count of tampering with evidence. The guilty plea resolves the question of guilt on those counts and shifts the court’s focus to sentencing factors, including the seriousness of the injuries, the defendant’s actions after the crash and any relevant prior record presented to the judge.

Cases involving leaving the scene typically examine whether a driver remained to provide identifying information and to assist injured people or notify emergency responders. Tampering allegations generally focus on actions taken to conceal, alter or remove evidence relevant to an investigation.

Officer’s injuries and the broader public-safety context

The crash drew public attention because of the extent of Spiess’s injuries and the circumstances in which he was hurt. In matters involving injuries to police officers, courts often receive detailed medical information and victim impact statements describing long-term physical limitations, follow-up treatment and broader effects on work and family life.

While the sentencing will address Carr’s criminal responsibility under the counts he admitted, it also comes amid heightened regional concern about highway safety and the risks officers face during roadside enforcement and arrests, particularly on high-speed interstates where secondary collisions can be catastrophic.

What happens at the hearing

At sentencing, the judge may review a presentence investigation report, hear arguments from prosecutors and defense counsel, and consider statements from the injured officer or family members if they choose to speak. The defense may ask for a sentence at the lower end of the permissible range or request alternatives such as treatment requirements, while prosecutors may argue for incarceration based on the conduct and the harm caused.

• Defendant: Frank Carr
• Injured officer: Nathan Spiess, St. Louis Metropolitan Police Department
• Admitted offenses: two counts of leaving the scene of an injury accident; one count of tampering with evidence
• Hearing time: 9 a.m. Tuesday

Sentencing hearings in cases involving severe injury can hinge on the defendant’s post-crash decisions as well as the lasting medical consequences for the victim.

The court’s decision will determine the penalties Carr faces for the crimes he has admitted, closing a major phase of the case while leaving open the possibility of additional civil proceedings that can arise in serious-injury crashes.
