Four people were injured, including one critically, in a Thursday afternoon wreck that temporarily blocked all lanes of Cobb Parkway in Marietta, according to police.

Investigators believe Thomas Dempsey, 78, of Cleveland, Ohio, lost control of his 2011 Toyota Highlander while on the exit ramp from the Canton Road Connector to Cobb Parkway, Officer David Baldwin with Marietta police said.

The Highlander traveled through the grass at a high rate of speed and hit a ditch, causing the vehicle to become airborne, Baldwin said. The SUV then landed on top of a brown 2000 Chevrolet Silverado pickup that was traveling northbound on Cobb Parkway, he said.

Both vehicles then slid across all lanes of Cobb Parkway before traveling down an embankment and hitting trees, Baldwin said. Two people in each vehicle were injured and transported to WellStar Kennestone Hospital, police said.

The crash left a passenger in the pickup truck, 25-year-old Anna Woodard of Marietta, in critical condition, according to police. The truck’s driver, Boris Woodard, 56, of Marietta, was in serious condition.

Dempsey and his passenger, Delann Dempsey, 73, of Cleveland, were both were listed in serious condition Thursday night, Baldwin said.

Charges are pending in the wreck, which remains under investigation. Anyone with information on the crash is asked to contact Officer Stephen Miller at 770-794-5356.
