A Thibodaux woman died Thursday afternoon in a four-vehicle crash on La. 70 in Ascension Parish, State Police said.

The crash happened shortly before 1 p.m. when Tiffany L. Moore, 41, of Thibodaux, failed to stop her 2007 Mercury Montego when approaching traffic congestion on La 70. south of La. 22, causing her to rear-end a 1999 Honda Accord driven by Jacqueline Harvey, 38, of Baton Rouge, said Trooper 1st Class Jared Sandifer, a State Police spokesman.

The impact pushed the Honda into another car that left the scene, Sandifer said in a news release.

Also, a 2006 Ford pickup truck driven by Adelin Rodrigue, 75, of Port Allen, failed to stop in time and rear-ended the Mercury, Sandifer said.

The collisions all happened about the same time, he said.

Moore, who was wearing a seat belt, was taken to St. Elizabeth’s Hospital in Gonzales where she later was pronounced dead, Sandifer said.

Harvey and Rodrigue also were wearing seat belts, and they suffered minor injuries. Rodrigue was issued a careless operation citation after the crash, Sandifer said.

Troopers do not suspect impairment as a factor in the crash, but routine toxicology samples from the three people were sent to the State Police Crime Lab for analysis.

Investigators are looking for the driver of the fourth vehicle, which is described as a dark-colored Honda Accord. Investigators do not believe that driver’s actions factored in to the crash, Sandifer said, but they would still like to speak with her.

Troopers ask anyone with any information to contact Louisiana State Police Troop A at (225) 754-8500.

Editor’s note: This article was changed on May 30, 2014, to reflect that Adelin Rodrigue was cited for careless operation, not Jacqueline Harvey.
