MONTGOMERY COUNTY, Ill. (WAND) – Two adults and two children are dead after a car crash in Montgomery County.

Illinois State Police say it happened Saturday night around 6:20 on Illinois Route 185 near Coffeen.

Officials say the ISP Traffic Crash Reconstruction unit is still investigating this case.

There will be a prayer vigil in remembrance of Bill and Jackie Protz and Jenna and Holly Sunday at 4 p.m at the Sullivan Courthouse on the south lawn. Everyone will gather, join hands and pray in unity with the Vandalia community. Pastor Kenny Bontrager will lead the prayer.
