A Denham Springs man was arrested following the single-vehicle crash early Monday that killed his twin brother, according to Louisiana State Police.
The crash happened shortly after midnight on LA 422 in Norwood, east of Highway 19 in East Feliciana Parish.
Taylor Scrantz, a spokesperson for Louisiana State Police, says the crash claimed the life of 27-year-old Edward Slaven III, of Denham Springs.
Scrantz says Slaven's twin brother, Edward Slaven IV, was driving eastbound on LA 422 in a Chevrolet Silverado when the vehicle left the roadway and struck a tree.
Slaven III was not wearing a seat belt and died at the scene, Scrantz said. Another passenger in the backseat, also unrestrained, sustained serious injuries and was taken to a hospital.
Scrantz said Slaven IV wasn't wearing a seat belt and sustained moderate injuries. After his release from the hospital, he was arrested and booked into the East Feliciana Parish Jail on one count each of negligent homicide, negligent injuring, careless operation, and driving under suspension.
While impairment is unknown at this time, a toxicology sample was taken from Slaven IV for analysis, Scrantz said.
The crash remains under investigation.
