Two Montgomery County families are mourning the loss of loved ones after a head-on crash Wednesday night.

Jenny Runnels was with her young daughter when she was killed in the accident. Her daughter who is a 4th grade student at Lone Star Elementary was critically hurt.

"Jenny is going to be sorely missed," said Roland Goodrum, a good family friend of Runnels. "She was like the backbone of the family."

Brian and Madelyn Fellman are students at Lone Star Elementary. Runnels had been a teacher for Montgomery ISD for the last three years.

"It was very sad," the Fellmans said, referring to the mood in school on Thursday. "It was very sad. People were crying a lot."

In addition to her daughter, Jenny leaves behind her husband Joe and a son named Dalton.

"It's going to be tough on Jo Jo. It's going to be tough on the family," said Goodrum. "It's tragic but only God knows. I know they're going through grief too but just two families destroyed overnight."

Floyd Nelms, 31, was driving the Impala. He died at the scene.

Friends say he was rushing home to take his 2-year-old son to the hospital for a high fever.

Co-workers at Storman Realty say he will be missed.

“He lit up our office with life and laughter,” Bryanna McGregor said. “He was often heard speaking of what the world could one day be like with no race or hate, just love and peace.”

Nelms is survived by his wife Tashona, his son Kai and stepdaughter Mica.

The crash remains under investigation. There is no word on what may have caused the accident.
