A Warren County deputy was flown to University of Mississippi Medical Center in Jackson this morning after being injured in a wreck on U.S. 61 North and Oak Ridge Road.

The condition of 38-year-old David Lambert was “undetermined” at 9 this morning, UMC spokesman Peggy Wagner said.

“No one has assessed his condition,” she said.

Lambert, a Warren County deputy since January, was taken to River Region Medical Center with head injuries before being transferred, said Mississippi Highway Safety Patrol Staff Sgt. Dennis Weaver, who was dispatched to the wreck scene at 3:45 a.m.

Weaver said later this morning that he believes Lambert was headed north “responding to a call for assistance.”

The investigation immediately showed that as Lambert passed the Oak Ridge Road intersection, he swerved to the left, hit the median and corrected before the cruiser, a Ford Crown Victoria, rolled and then came to rest on the east shoulder.

“It looks like he was avoiding something coming from his right at the intersection,” said Weaver.

“Right now, we’re working on seeing if another vehicle contributed to the wreck,” he said. If the car’s blue lights were running, a dashboard camera should automatically have been rolling and possibly will show what happened.

Two sets of tire marks were found at the intersection, and those belonging to the second car were acceleration marks, Weaver said.

“Normally, you don’t see acceleration marks like that at an intersection,” he said. “People don’t usually squeal their tires at a green light.”

Before coming to Warren County, the father of three stepchildren, whose wife is a nurse at River Region, was employed with the Ross Barnett Reservoir Patrol from 2008 to December 2009. He worked in security for River Oaks Medical Center in Jackson from 2006 to 2008 and for UMC police from 1995 to 2006, Warren County Sheriff Martin Pace said.

The sheriff this morning described Lambert as a “very professional and dedicated officer who came to us with several years in law enforcement.”

Lambert also has seven step-grandchildren.
