A Macomb man involved in a rear-end crash on Wednesday was life-flighted to a hospital with serious injures.

The wreck happened on Illinois Route 336 in McDonough County around 2:51 p.m.

According to a preliminary Illinois State Police investigation, the driver of a Mack concrete truck, Mitchell L. Van Bebber, 51, of Colchester, was travelling westbound on Illinois Route 336 east of County Road 150E and slowed down for a truck that was turning in front of his vehicle.

The driver of a Ford F250 pickup truck, R. H. Swan, 50, of Macomb, did not see the Mack truck slow down and rear ended it, according to ISP.

Swan was flown to a regional hospital with serious injuries. Bebber was not injured.

No charges have been filed pending a complete investigation.
