A Lake Charles man was killed last week after authorities said excessive speeds contributed to a violent and deadly Bonnet Carre Spillway wreck.

The crash occurred at 10:20 a.m. Friday on I-10 west at milepost 214 on the Bonnet Carre Spillway in St. Charles Parish, according to Louisiana State Police Troop B.

Trooper Melissa Matey said the crash involved two vehicles and one of the drivers, 34-year-old Paul J. Dellafosse of Lake Charles, was taken to University Medical Center, where he later died.

“Preliminary investigation revealed that Dellafosse was operating a 2002 Honda Accord at a high rate of speed on I-10 west,” Matey said. “For reasons under investigation, the Honda struck the left curb, which caused it to enter the right lane.

“It then struck a 2010 Ford Focus, driven by 20-year-old Steven Kimelman of Winter Springs, Fla., that was traveling in the right lane.”

Police said the Ford and Honda struck the right guardrail and the Ford came to rest in the right lane and the Honda flipped onto its roof.

Dellafosse and his passenger, 37-year-old Kevin Simmons of Boutte, was properly seat belted. However, Dellafosse sustained serious injuries and died at the hospital late Friday night. Simmons was not injured.

Kimelman and three occupants from Florida in the Ford were properly seat belted and no injuries were reported.

Impairment is not considered to be a factor of the crash.
