Married for 30 years, they were both teachers in the Grand Prairie Independent School District in Grand Prairie, Texas. According to their son, his parents worked up until they became sick in early December. "Doctors said they hadn't seen any progression at all, and they were slowly declining in their overall vital functions," said Blackwell. "It got to the point where it was very far gone and that there was nothing else they could do."
