The mother of Baton Rouge state Sen. Dan Claitor died late Wednesday after she was injured in a Saturday crash on Airline Highway in Ascension Parish, State Police said Thursday.

Nancy M. Claitor, 80, of Baton Rouge, died at Our Lady of the Lake Regional Medical Center in Baton Rouge shortly before midnight Wednesday, the State Police said.

Dan Claitor is a Baton Rouge Republican and also a candidate for the 6th Congressional District.

Troopers have said the crash happened about 12:30 p.m. Saturday on Airline Highway near Old Perkins Road close to the East Baton Rouge-Ascension Parish line.

Nancy Claitor, the driver, was in the right-hand lane of Airline, and a 2005 Dodge Ram pickup pulling a large trailer was behind her in the left lane, troopers said.

Claitor shifted her 2013 Ford Explorer into the left lane in front of the truck as she tried to make a legal U-turn, but she stopped. The truck rear-ended her Explorer, Jared Sandifer, a State Police spokesman, has said.

The collision sent Claitor’s Explorer into the median, he said.

Claitor’s husband and the front-seat passenger, Robert Claitor, 88, also of Baton Rouge, was taken to the hospital but had minor injuries, troopers have said.

Neither driver is suspected of being impaired by alcohol or drugs, and both were wearing their seat belts, troopers have said.

The driver of the pickup, Henry Johnson, 37, of Prairieville had minor injuries and refused medical treatment, troopers have said.

The crash remains under investigation, but no charges have been filed, trooper said Thursday.
