Sandy Springs police arrested a driver on murder charges after he allegedly hit and killed an Atlanta real estate investor last month.

Bryan Keith Schmitt, 47, of Sandy Springs, was arrested Monday in connection with the death of Hamid Jahangard, 60. Investigators believe Jahangard died as a result of a road-rage incident.

Jahangard was hit July 30 by Schmitt’s Mercedes sedan, according to police. Officers responding to the scene found the man lying on a sidewalk near a home in the 300 block of River Valley Road. He died three days later at a hospital.

The Fulton County Medical Examiner’s office confirmed to Channel 2 Action News that Jahangard died of “blunt force injury of the head.”

Police continued to investigate in the weeks following his death, determining the impact of the collision caused Jahangard to fall and hit his head, police spokesman Sgt. Sam Worsham said.

After the July 30 incident, Schmitt stayed at the scene and spoke with officers, Worsham said. Schmitt, who has been an attorney in Georgia since 2015, is facing charges of malice murder, felony murder and aggravated assault.

He waived his first hearing, which was scheduled for Tuesday, and he remains in the Fulton County Jail without bond, the Fulton County Sheriff’s Office said.

GoFundMe page  set up to support Jahangard's two adult daughters had raised nearly all its $5,000 goal as of Monday afternoon.
