Knoxville, TN: Two people injured in Multiple vehicle crash in Knox County on Saturday October 17 2015

Three Knox County deputies and a state trooper were injured early Saturday morning in a multiple vehicle crash. The man who hit them is being charged with DUI.
The incident began shortly before 1 a.m. Saturday when a couple driving down I-75 North began arguing.
The woman was driving, and her husband grabbed the wheel forcing the car into the concrete guard rail between Emory Road and Raccoon Valley. She received injuries and was taken to UT Medical Center for treatment. He fled the scene.
Trooper Michael Herrell was investigating the crash on I-75 northbound around the 113 mile marker on the right shoulder. That’s when Earl Lipscomb of Clinton was driving past the crash scene and struck the first KCSD unit causing it to rotate and strike the THP unit with its driver’s door, which caused the THP unit to hit two Knox County deputies next to the guard rail.
After hitting the THP unit, Lipscomb’s Chevrolet Impala struck the third Knox County deputy. Lipscomb’s car stopped facing south in the north bound lanes across both lanes of travel.
THP reported that Trooper Michael Herrell, Deputy Jason Overton, Deputy Anthony Rathbone, and Deputy Heath Stone received injuries. The extent is unknown at this time.
Earl Lipscomb has been charged with failure to maintain lane, failure to due care, failure to move over, DUI, and four counts of felony reckless endangerment.
