A woman stabbed a convicted sex offender to death over the weekend as police said the felon attempted to rape her inside a Louisiana business in broad daylight.

The Blake Prestonattack took place at a laundromat in Lacombe, a small, rural community about a 50-mile drive northeast of New Orleans.

The St. Tammany Parish Sheriff’s Office reported deputies responded about 3:30 p.m. Sunday to a laundromat off U.S. 190 for a report of unresponsive man with an apparent stab wound.

While en route to the scene, deputies were also dispatched to a call in reference to a woman claiming she stabbed a man who had attacked her while she was at the same laundromat.

Arriving officers found 40-year-old Nicholas Tranchant at the business suffering from a stab wound, officials said.

Tranchant was taken to a hospital where he died, according to a press release from the department.

A preliminary investigation into the death determined Tranchant − a convicted sex offender − entered the business armed with what officials described as a sharp weapon, and attempted to sexually assault the woman.

But she fought back.  

"The female was able to gain possession of the weapon, and used it to stab him before fleeing to safety," the department wrote in the release.

The woman was also taken to a hospital to be treated for injuries suffered in the attack, the department said.

“I want to compliment this brave woman on the courage and strength she showed in fighting back against her attacker and ask for prayers for her continued recovery,” Sheriff Randy Smith said.
