Douglas Ziemann, 67, was traveling west about 2:40 p.m. Tuesday on Howe Road and turned left onto Wonder Woods Drive, McHenry County Sheriff’s Deputy Sandra Rogers said in an email. Rogers said she did not know Ziemann’s hometown.
The bicyclists were heading east on Howe Road at Wonder Woods Drive when Ziemann struck one. The other hit the side of the vehicle.
When firefighters arrived, a male bicyclist was on the ground in front of the minivan. The van had the indentation of a body in its windshield, Wonder Lake Fire Deputy Chief Mike Weber previously said. A female bicyclist had struck the side of the van and was thrown over her handlebars.
Rogers said both riders were conscious and responding on the scene.
Responders called Flight For Life for the man, who was in critical condition, but the local helicopter already was responding to airlift an individual from Spring Grove, where a man needed to be freed from his truck after he struck a tree.
Another Flight For Life helicopter was en route from Waukesha, Wisconsin, but it was deemed its estimated time of arrival was too long to wait.
Both the man and woman were taken via ambulances to Centegra Hospital – McHenry. The woman suffered injuries not considered to be life-threatening. One was later flown to Advocate Condell Medical Center in Libertyville, Rogers said.
Weber said the man remained in critical condition Wednesday.
The 67-year-old was issued a citation for failing to yield while turning left.
