A 5-month-old infant died after a two-vehicle collision shortly before 6 p.m. Tuesday on U.S. 61 at La. 73 in Ascension Parish, State Police reported.

The child, Emanuel Lange Jr., was properly secured in a 2006 Mercedes CLS500 driven by Tennille Willis, 35, of Baton Rouge, said Sgt. Jared L. Sandifer, a spokesman for Louisiana State Police Troop A.

Willis, headed north on U.S. 61, was driving through the intersection at La. 73 on a green light, Sandifer said.

Adria M. Brignac, 31, of St. Amant, driving a 2005 Nissan Pathfinder south on U.S. 61, attempted to make a left turn onto La. 73, pulling into the path of the Mercedes, Sandifer said.

The Pathfinder struck the Mercedes on its driver’s side, causing it to leave the highway and strike a traffic light pole, Sandifer said.

The baby, who suffered serious injuries, was transported to Our Lady of the Lake Regional Medical Center in Baton Rouge where he later succumbed to injuries received in the crash, Sandifer said.

Willis and a 13-year-old girl, both properly restrained, suffered moderate injuries and also were transported to OLOL, the trooper said.

Brignac, who was not injured, was cited with improper left turn at an intersection.

This crash remains under investigation, and further charges may be pending, Sandifer said.

He said impairment is not suspected of either driver.
