A 38-year-old Park Forest man has been sentenced to seven years in prison for causing the death of a 16-year-old Beecher girl in a car accident in 2017. Dustin Greiner was sentenced by Judge David Carlson for the accident which was caused by Greiner while driving under the influence of a controlled substance. The death occurred following an accident in which the vehicle Greiner was driving struck the back of the Ford Ranger in which the victim had been a passenger. The Ford Ranger was pushed into oncoming traffic by Greiner’s vehicle and struck by a Dodge Ram on the passenger side where the 16-year-old girl was seated. A urine test following the deadly accident revealed the presence of cocaine in Greiner’s system. Although Greiner’s license was suspended during the court proceedings, it was discovered that he drove on a suspended licensed after an initial sentencing hearing September 26th.
