Jury Convicts Maryland Man in 2022 D.C. Vehicular Homicide

A jury in D.C. Superior Court convicted Spiro Stafilatos, 38, of Silver Spring, Maryland, on charges of vehicular homicide and assault for the December 2022 death of pedestrian Shuyu Sui, the U.S. Attorney for the District of Columbia announced on May 6, 2026.

The verdict covers one pedestrian fatality and associated assault counts. Stafilatos struck Sui with his vehicle in the District of Columbia in December 2022. The U.S. Attorney’s Office presented evidence that resulted in the jury’s guilty finding on all counts.

The conviction changes the case status from pending trial to post-verdict sentencing. U.S. District Court procedures now require a presentence investigation report, followed by a sentencing hearing. Federal sentencing guidelines for vehicular homicide carry potential imprisonment ranges measured in years, mandatory restitution to the victim’s estate, and possible permanent revocation of driving privileges.

Sentencing date has not been set.

Downstream effects include formal entry of the conviction on Stafilatos’s criminal record, which bars him from firearm possession under federal law and triggers collateral consequences for employment and housing. The U.S. Attorney’s Office must prepare a sentencing memorandum outlining the government’s position on penalty.

The victim’s family gains the right to submit an impact statement that the court must consider before imposing sentence. Any appeal must be filed within 14 days of final judgment.

This marks the resolution of a 2022 incident that remained in pretrial status until the 2026 trial. The U.S. Attorney Jeanine Ferris Pirro’s office handled the prosecution in D.C. Superior Court under local statutes incorporated into federal charging authority for the District.
