DuPont has settled one of the lawsuits brought by the families of four workers killed in a fatal gas leak at DuPont's La Porte plant in November, 2014, according to the Houston Chronicle.

The estate of Crystle Wise, represented by her daughter Jasmine, has reached a confidential financial settlement, according to statements issued by DuPont and the Wise family attorney. Wise, an operator at DuPont's Lannate Unit, was killed last November when nearly 24,000 pounds of toxic methyl mercaptan spewed into a tower housing a pesticide manufacturing unit at the plant just outside Houston.

The settlement's terms require DuPont to observe a nationwide moment of silence for the next decade on the anniversary of the tragedy and to make a contribution to the American Humane Society in Wise's name, according to an email statement issued on behalf of the Wise family. Wise, who only recently had accepted a job with DuPont to be closer to her daughter in Houston, was an animal lover who regularly opened her home to strays.

DuPont spokesman Aaron Woods confirmed that a settlement had been reached via email to the Chronicle but added "the terms of the settlement are confidential so we cannot comment further."

Shift supervisor Wade Baker, along with brothers Robert and Gilbert Tisnado, also perished in the massive toxic gas leak, which remains under investigation by environmental authorities and by the U.S. Chemical Safety Board. The Baker and Tisnado families are are suing DuPont in other civil lawsuits pending in Harris County.

An interim report by the U.S. Chemical Safety Board that was highly critical of DuPont and its lax safety practices, as well as equipment, design and procedural failures that put both workers and the community at risk.
