Detectives with Louisiana State Police arrested a Maringouin woman after she admitted she called the State Police Crime Lab posing as an official with the 18th Judicial District Court in an attempt to have her toxicology evidence in a drunken driving case destroyed.

Jana L. Pourciau, 23, was booked Thursday into the East Baton Rouge Parish Prison on counts of false personation and forgery, Trooper 1st Class Jared L. Sandifer said in a news release.

On April 12, shortly before 11 p.m., troopers had responded to a single-vehicle crash on La. 977 south of La. 77 in Pointe Coupee Parish, Sandifer said.

Troopers determined Pourciau, while traveling northbound on La. 977, had lost control of her 2010 Lexus RX350, running off the road, striking the fence of an elementary school and overturning the car.

Troopers believed Pourciau was impaired at the time of the crash, and she was arrested and issued a summons for first-offense DWI, careless operation and no seat belt, Sandifer said. She was then transported to Baton Rouge General Medical Center Mid-City for injuries sustained in the crash, and while there a toxicology sample was obtained from her by medical personnel, he said.

On Tuesday, Pourciau called the State Police Crime Lab from her cell phone. Using a fictitious name, she falsely informed Crime Lab employees she was an employee of the 18th Judicial District Court, and said blood evidence from her crash could be destroyed “because the case had been dismissed and was not going to be prosecuted,” Sandifer said.

She then sent an email from her personal email account to the Crime Lab stating the same, he said.

When questioned by detectives, Pourciau admitted to calling and emailing the Crime Lab in an attempt to have the evidence destroyed, Sandifer said.
