Investigators are sorting out what happened after a Charleston County deputy shot a man who was said to have tried to grab the deputy's gun after a traffic stop Sunday afternoon.

The driver's name, the charges he might face and his medical condition were not released Sunday.

The deputy was placed on administrative leave, which is standard procedure during an investigation, sheriff's Maj. Jim Brady said.

Here's what led up to the shooting, according to Brady:

Shortly before 12:30 p.m. Sunday, a caller reported that a U-Haul truck was driving erratically on U.S. Highway 17 north near McClellanville. A female deputy spotted the truck and noticed it was still driving erratically. The deputy turned on her blue lights, but the driver refused to pull over. She followed the truck into Georgetown County.

After about 3 miles, the driver pulled into Pole Yard boat landing and got out. He failed to cooperate and the deputy used a Taser on him, according to Brady.

The driver continued to struggle and tried to grab the deputy's gun. She broke free and the man took off running. The deputy fired twice, hitting the driver in the torso and arm. Georgetown County EMS took the man to a local hospital.

The State Law Enforcement Division is investigating, with assistance from the Georgetown County Sheriff's Office.
