City police have arrested the driver in a two-month-old fatal crash on I-10 westbound in Ascension Parish that killed a Baton Rouge man, officers said.

Gonzales Police said Monday that John D. Sanchez, 27, turned himself in to the Gonzales Police Thursday after a toxicology report came back from tests taken after the Feb. 22 crash. Charlotte Guedry, police spokeswoman, said Monday she did know the results of the report.

Floyd Cox, 66, 8269 Greenwell Springs Road, Baton Rouge, was killed in the collision with Sanchez.

Sanchez, who was driving a 2003 Acura RSX westbound, hit Cox’s 2004 Isuzu Rodeo, sending it airborne off I-10 westbound with it landing on Boudreaux Road in Gonzales, Police Chief Sherman Jackson said in a news release.

Sanchez told police at the time that he was speeding to get to work, police said.

After his release in late February from St. Elizabeth Hospital in Gonzales, Sanchez, 11476 Benton Fredric Road, St. Amant, was cited on counts of reckless operation and driving with a suspended driver’s license.

Sanchez was arrested Thursday and booked into Ascension Parish Prison near Donaldsonville with a single count of negligent homicide. He remained in jail Monday in lieu of $100,000 bail, Jackson said.

Under Louisiana’s negligent homicide statute, the count can be brought when someone is killed in a vehicle crash and the responsible driver’s blood-alcohol content contributed to the death.
