Westmont Man Found Guilty of Aggravated DUI in Deadly Crash

DuPage County State’s Attorney Robert B. Berlin announced today that Onecimo Vazquez-Velazquez, 31 (d.o.b. 10/31/1987) of Westmont, has been found guilty of Aggravated DUI Causing Death and Reckless Homicide involving a 2018 crash that claimed the life of his passenger, Annajeanne Dewey. Judge Liam Brennan rendered his verdict this afternoon following a three-day bench trial. In all, Judge Brennan found Vazquez-Velazquez guilty of one count of Aggravated DUI Causing Death (Class 2 Felony) and two counts of Reckless Homicide (Class 3 Felony.) 


  On October 7, 2018, at approximately 1:00 a.m., Vazquez-Velazquez was traveling at a high rate of speed northbound on Fairview Avenue near the intersection of 55th Street in Downers Grove. As Vazquez-Velazquez attempted to pass a car by entering the oncoming lane of traffic, he lost control of his vehicle and crashed into a tree, splitting the vehicle in half and killing Dewey. Vazquez-Velazquez was interviewed by officers who observed a strong odor of alcohol on his breath as well as glassy and bloodshot eyes. Vazquez-Velazquez’s BAC was .077 approximately one and a half hours after the crash. Vazquez-Velazquez was taken into custody and appeared at a bond hearing on October 11, 2018 where Judge Brennan set bond at $500,000 with 10% to apply. He has remained in custody at the DuPage County Jail since that time. 


“Just over one year ago, Annajeanne Dewey was killed in a crash so horrific it split the vehicle in which she was a passenger in half,” Berlin said. “An investigation into the crash revealed that the driver of that vehicle, Onecimo Vazquez-Velazquez had been drinking before getting behind the wheel. Sadly, because of the irresponsible and reckless actions of Mr. Vazquez-Velazquez, Annajeanne’s life was taken from her as she took her place as a statistic of drunk driving. I offer my sincerest condolences to Annajeanne’s family and friends on their tremendous loss. I would like to thank the Downers Grove Police Department, the DuPage County Sheriff’s Office as well as the FIAT Major Crash Reconstruction Team for their work on this very sad case. I would also like to thank Assistant State’s Attorneys Tom Minser and Nick Noble for their outstanding work in holding Mr. Vazquez-Velazquez responsible for the death of Annajeanne Dewey.”


Vazquez-Velazquez’s next court appearance is scheduled for November 20, 2019 for return of the Pre-sentence Report.
