ST. HELENA PARISH - A 911 dispatcher was killed early April 16 after her vehicle was struck head-on by a suspected impaired driver.

State Police said 45-year-old Grace Chandler died in the crash on LA-16 near Calmes Road in St. Helena Parish. 

June 11, nearly two months after the accident, a Denham Springs man was arrested for the accident. 

Troopers said 28-year-old Nicholas Carter was booked for vehicular homicide, third-offense DWI, operating a vehicle while license is suspended, failure to drive on the right side of the road and speeding. 

The Tangipahoa Parish Sheriff's Office and Tangipahoa Parish 911 posted on social media mourning the loss of Chandler, a Communications Operator at the Tangipahoa 911 Center.

Troopers said Chandler was driving east on LA 16 when Carter was driving west on the highway. Carter's vehicle reportedly crossed the center line and entered the eastbound lane, striking Chandler's vehicle head-on.

Chandler sustained fatal injuries and died at the scene. Carter was transported to a hospital with serious injuries. Both drivers were wearing seatbelts, according to police.

Police suspect that Carter was driving impaired, and a toxicology sample was taken from him for analysis. A toxicology sample was also taken from Chandler, but she is not suspected of being intoxicated at the time of the crash.

This is an ongoing investigation.
