One of the teachers killed in the mass shooting at Santa Fe High School in Texas is a former Baton Rouge resident, according to information posted to Facebook. 

Cynthia Tisdale, a substitute at the school, was one of two faculty members killed along with eight students when Dimitrios Pagourtzis opened fire on Friday. 

Family members confirmed that Tisdale was among the victims killed in the shooting.

A Facebook account under the same name listed Tisdale as a Broadmoor High School graduate, currently living in Dickinson, Texas. She was originally from Thibodaux. 

Tisdale's niece, Leia Olinde, said Tisdale was like a mother to her and helped her shop for wedding dresses last year.

"She helped me put it on, she helped fix my hair," Olinde said through tears.

"She was wonderful. She was just so loving," said Olinde, 25. "I've never met a woman who loved her family so much."

She said Tisdale was married to her husband for close to 40 years and that the two had three children and eight grandchildren.

Tisdale's house was the center for family gatherings, and she loved cooking Thanksgiving dinner and decorating her house, Olinde said.

Olinde's fiance, Eric Sanders, said of Tisdale that "words don't explain her lust for life and the joy she got from helping people."
