A US man carried out an "intentional act of violence" when he allegedly drove at a pregnant woman and a 2-year-old child, killing them and her unborn baby, according to police.
William Phillips was taken to the Jefferson County Justice Center, following the incident earlier this week, where he was charged with two counts of first-degree murder and one count of attempted first-degree murder.

A statement from the Jefferson City Police department on Facebook said initial reports suggest it was an "intentional act of violence" toward randomly chosen pedestrians.
Sierra Wilson Cahoon, her son Nolan, and her unborn child died at the scene.
Investigators have determined Phillips did not know the victims, police said.
"He swerved and intentionally struck a pedestrian. He then travelled less than a mile where again swerved and intentionally struck the next two victims."
Police said the first pedestrian, Tillman Gunter, was taken to hospital with life-threatening injuries.
