The driver who led deputies on a 100 mph chase Monday on Interstate 26 sold “a quantity” of cocaine before fleeing, then tossed more cocaine out the window while deputies were pursuing him, according to an incident report released Wednesday by the Charleston County Sheriff’s Office.

Here are more details from the report:

About 7:45 p.m., a confidential informant bought cocaine from the driver of a white Lincoln Navigator in a parking lot near Magwood Drive and the Glenn McConnell Parkway. A uniformed deputy approached the SUV with his gun drawn and ordered the driver to get out.

The driver took off, leading deputies on a chase to downtown Charleston, back into West Ashley and onto I-26 toward Columbia.

Deputies backed off near Orangeburg.

Deputies said they saw the driver toss a bag containing a white powder out the window in the South Lenevar neighborhood in West Ashley, and another baggie with a white substance inside onto I-26 in Dorchester County. The baggie that was tossed in West Ashley was recovered and found to contain 5.2 ounces of cocaine. The one that was tossed onto I-26 was not found.

Investigators were tracking down the driver’s identity so they could issue warrants for failure to stop for blue lights and trafficking cocaine, according to the report.
