CHARLOTTE, N.C. -- A Charlotte couple was among those injured in the Boston Marathon explosions Monday afternoon.
Nicole Gross, 31, a personal trainer at Charlotte Athletic Club, was at the finish line with her husband Michael when the explosions went off; they were waiting for her mother to complete the 26.2-mile race.
Both remain in a Boston hospital according to Michael's brother, Brian Gross, who lives in Fort Mill.
Brian spoke with NBC Charlotte Tuesday morning about his brother and sister-in-law.
"They're doing good," Brian said of his brother and sister-in-law. "Nicole was in surgery last night and she was stable going into it, but she needs to go back into surgery today to get some more work done."
Nicole's sister was with them during the race and lost her leg from the knee down, according to Brian.
"Her sister is at a different hospital they were able to locate her last night, it took all day," Brian said. "She is in critical condition, both legs were injured. From what I understand, my brother said, one of her leg's was amputated from the knee down."
Brian said he was at work when he first heard about the bombings, and shortly after that his phone and e-mail was flooded with concerned family and friends.
"I did end up hearing, shortly after the bombs took place, that my brother, Nicole and her sister, Erica, were injured. Erica and Nicole, Micheal was not able to find them."
