Dallas ? Two children struggled Wednesday morning before their mother threw them 22 feet from an overpass into oncoming Interstate 30 rush-hour traffic, Dallas police said.

Khandi Busby, 27, then jumped herself from the overpass railing, police said.

“The children were trying to stave off being thrown over the edge, but they were overpowered by their mother,” said Dallas police Lt. C.L. Williams.

Busby faces possible charges of attempted capital murder, Janse said. She was listed in fair condition at Baylor University Medical Center at Dallas late Wednesday.

The boys were in good condition, police said. Officials at Children’s Medical Center in Dallas would not comment on the children’s condition, citing privacy rules.
