LOWELL | An early Saturday snowstorm is being blamed for a traffic accident that briefly closed a south Lake County section of Interstate 65 and left a downstate man injured.

Indiana State Police said Kevin Tomeo, 30, of Avon, In., west of Indianapolis, suffered head and internal injures. He was transported to St. Anthony Medical Center in Crown Point.

The National Weather Service said Saturday an overnight snow system deposited a half inch of snow across much of Northwest Indiana.

Police said an unidentified passenger car was southbound on I-65 shortly after 3 a.m. Saturday when it lost control on a patch of black ice that formed from snow melt at the 238 mile marker, two miles south of the Indiana 2 exit.

Police said the passenger car pulled out of the skid and continued unharmed, but Tomeo's Jeep Cherokee, which was traveling behind it, lost control when he attempted to brake to avoid a collision.

Police said the Jeep began spinning, hit the guard rail and bounced back onto the highway where it was hit by a 2003 Mack truck pulling a double trailer.

Police said the tractor trailer jackknifed, hit the guard rail on the right side of the pavement and came to a halt, blocking all southbound lanes of travel for two and a half hours.

Police said the tractor trailer driver, Roosevelt Bell, 28, of Park Forest, Ill., was uninjured, but ticketed for driving too fast for road conditions.

The National Weather Service said temperatures will remain in the low 30s, but no more snow is forecast until Tuesday.
