Two Women Dead After One-Vehicle DUI-Related Crash On I-64

Two women, Chelsea M. Dunn, 20, of Mount Vernon, and Wilyssa B. Moore, 19, of Mount Vernon are dead following a single vehicle DUI crash on the eastbound lanes of I-64 near mile marker 54, at 1 a.m., on Friday, July 29.

The vehicle in question was a 1993 Cadillac driven by Zacchaues Williams, 31, of Saint Louis, which Dunn and Moore were passengers in, along with Jessica M. McSwain, 30, of Mount Vernon.

According to the Illinois State Police, “Preliminary investigative details indicate the Cadillac was traveling on I64 East Bound at Mile Post 54 in the left lane. For an unknown reason, the Cadillac left the right side of the roadway and entered onto the shoulder where it struck a tree.”

At approximately 1:20 a.m., the office of the Washington County Coroner Mark Styninger was dispatched to the scene of the accident. Their report states, “an older model Cadillac traveling east bound, apparently left the roadway and traveled 27 yards while rolling over and striking a tree on the south side of the highway, resting on its side.”

Both Dunn and Moorer were pronounced dead at the scene at 1:45 a.m. by Washington County Coroner Mark Styninger.

Styninger’s report added that, “both victims had to be extricated from the vehicle by the Nashville Fire Department.”

Williams was air lifted from the scene to a St. Louis hospital and was in serious condition. McSwain was transported to SSM Good Samaritan Medical Center in Mt. Vernon, and was listed as being in good condition.

The roadway was closed for approximately one hour for crash investigation and clean up.

Williams, Dunn and Moore were all unrestrained. McSwain was the only occupant of the vehicle wearing a seatbelt.

Following the accident, Williams was charged with driving with No Valid Driver’s License, Improper Lane Usage, and Driving Under the Influence.
