A jury returned guilty verdicts this week in connection with the drunk-driving crash that killed two relatives and forced postponement of a family wedding.

Leavenworth County Attorney Todd Thompson said the jury returned guilty verdicts against William “Willie” Wilson, 24, for the crash June 13.

Deputies responded to the crash on County Road One just north of Eudora, Kan. at about 5am. Thompson says a vehicle had veered off the road and into a tree. The defendant was the only one found alive at the scene. Justin Wilson and Jessie Aldrich were killed after being ejected from the vehicle. No one was wearing a seat belt.

Thompson said the defendant was just 20 years old, and thus was not legally allowed to be drinking. When the officers arrived at 5 am, they found he had a .09 blood-alcohol reading. It is believed the trio had left a drinking establishment together at around 2 to 3 am.

All three were slated to be groomsmen in a wedding later that Saturday at Holy-Field Vineyard and Winery in Basehor, which is where they lived. Thompson says the wedding between Zach Wilson and Shanna Breuer was postponed due to the tragedy. Willie Wilson was the brother of the groom and also related to the victims.

The jury trial started Monday and ended Tuesday afternoon at 4 pm. Shortly after 8 pm the jury found Wilson guilty of involuntary manslaughter due to DUI.

Sentencing is set for July 21, at 11 am. The crime of an involuntary manslaughter is a level 4 person felony crime and includes presumptive prison.

County Attorney Todd Thompson said, “This was a horrible tragedy all the way around. This is devastating to a family. Events like weddings generally involve alcohol, but everyone must be remember to be responsible. I hate that this has to be another example of the importance of a designated driver, cab, uber, and the use of seatbelts.”
