Idaho State Police are still asking for public help to determine how a 4-inch by 4-inch piece of lumber got airborne and smashed through the windshield of a pickup truck in the eastbound lanes of Interstate 84 by Meridian Wednesday morning.

Police say the pickup was headed eastbound on 1-84 between Ten Mile and Meridian roads around 8 a.m. Wednesday when a piece of a wooden fencepost smashed through the windshield and seriously injured the driver, a 31-year-old man. Police say the wood could have come from a car or other vehicle carrying lumber going westbound on I-84 in the same area.

The driver was badly injured in the crash but appears to be getting better. He was listed in critical condition on Wednesday at Saint Alphonsus Regional Medical Center but that listing was upgraded to fair condition by Friday.

ISP officials have not been able to find anybody who saw what happened as of Friday morning but are still hoping to find witnesses, since there were several vehicles on the highway around the time of the crash.

Police would like to talk to anybody who saw what happened or noticed a vehicle losing lumber on I-84 around 8 a.m. Wednesday. Anyone with information should call 846-7500.
