A 67-year-old man and his four-year-old grandson were killed late Wednesday after the pickup truck they were in ran off a road and flipped over in a canal, Iberville Parish Sheriff’s Office Maj. Johnny Blanchard said.

Deputies were called to the scene on Kurt Creek Lane just outside of Plaquemine, at 11:40 p.m., Blanchard said.

When deputies arrived, the truck was upside down in the canal and both occupants were dead, Blanchard said.

Charles Werchan, who lived on Kurt Creek Lane, was the driver who was killed, Blanchard said.

Werchan was driving his grandson, Brennan Newman, home to Addis when the fatal wreck occurred, Blanchard said.

Wednesday’s night’s rough, rainy weather may have played a part in the crash which remains under investigation, Blanchard said.
