BERKELEY COUNTY, SC (WCSC) - EDITOR'S NOTE: The video attached to this story does not show the actual crash.
The Berkeley County Sheriff's Office released dash cam video of a high-speed chase that ended with the death of a motorcyclist Wednesday night.
The motorcyclist, Robert Lee Clark, Jr., 30, of Goose Creek, was declared dead at the scene, authorities said.
A deputy on patrol on College Park Road at approximately 11:51 p.m. Wednesday spotted a motorcycle speeding toward Crowfield Boulevard from the direction of I-26, according to Chief Deputy Mike Cochran.
Deputies say the motorcycle was traveling approximately 66 mph in a posted 45 mph zone.
The motorcyclist sped up and refused to stop when the deputy turned on his blue lights, a release from the sheriff's office states.
Speeds in the ensuing chase reached up to 111 mph at times with the motorcyclist slamming on the breaks and then speeding away several times.
Cochran said the pursuit continued up College Park Road, then onto Highway 17A and then West 1st Street in Summerville, covering a total of approximately 7.75 miles over five-and-a-half minutes.
At the end of the pursuit, the motorcyclist applied the brakes sharply and the motorcycle slowed rapidly, then swerved to the right in an apparent attempt to go around a vehicle that had yielded for blue lights, the release states.
When the motorcyclist attempted to accelerate away, the operator appears to have missed a gear while the motorcycle continued to slow, causing contact between the motorcycle and the front right corner of the deputy's vehicle, Cochran said. This caused the motorcyclist to lose control and strike the curb between the vehicle that had yielded and the sidewalk.
Video released by the Berkeley County Sheriff's Office on its YouTube channel shows the entire incident including the fatal crash. That video is graphic and may be very disturbing. The video can be viewed here.
The deputy involved has been placed on administrative leave pending an administrative review, Cochran said.
The Highway Patrol is investigating the crash and the Berkeley County Sheriff's Office is conducting an internal investigation parallel to the SCHP investigation.
