Man Held on Aggravated DUI and Reckless Homicide Charges After Fox River Pontoon Crash

Detention followed prosecutors’ presentation of hospital blood tests and witness accounts in the fatal collision.

Overview

  • A 31-foot pontoon allegedly struck a 20-foot Crownline on the Fox River on Saturday, July 25, killing 48-year-old Magdalena Jablonska and injuring her fiancé and their dog.
  • Authorities arrested 45-year-old Richard M. Stevenson and charged him with two counts of aggravated DUI causing death and one count of reckless homicide after hospital bloodwork showed a blood-alcohol concentration of about 0.200.
