Granados' twin sister, Rosie Granados, told CNN she heard Mary Granados scream while the women were talking on the telephone.

“It was very painful,” Rosie Granados told the network. “I just wanted to help her and I couldn’t. I thought she had got bit by a dog or something. I tried calling her name and she wouldn’t answer.”

The Granados sisters moved from Juarez, Mexico, to Odessa when they were 14, according to CNN. Mary Granados had been employed by the USPS for about a year, her sister said.
