A man died Wednesday morning when a piece of concrete smashed through the windshield of his pickup truck and hit him, Nicholasville police said.
Jessamine County Coroner Michael Hughes identified the man as Michael Conley, 63, of Nicholasville. The object hit Conley in the head, and he likely died instantly, Hughes said.
Police Sgt. Scott Harvey said it was unclear whether the object fell from another vehicle or had been kicked up by traffic. The pickup came to rest against a guardrail without striking any other vehicles, according to police.
The accident occurred just before 9 a.m. on Catnip Hill Road.
Harvey described the object as a "chunk of concrete ... smaller than a football, but larger than a softball."
Accident reconstruction crews were there as of 10:25 a.m. Wednesday, and traffic was shut down, Harvey said.
He said the truck apparently traveled some distance after being struck by the rock. Officers are trying to pinpoint just where the impact occurred, he said.
Police also are interviewing witnesses and will check surveillance video in hopes of determining whether the rock fell from another vehicle or was thrown up by traffic, Harvey said.
