The driver of the minivan and a 2-year-old boy in the vehicle were not injured.

St. Louis County police refused to identify the minivan driver, saying her lawyer told police she had “observed many threats on social media.”

St. Louis County Officer Shawn McGuire said police had not seen specific threats aimed at the woman but had seen comments on social media and news articles about the woman.

“We reasonably believe the passionate posts on this topic will turn into specific threats” if the name were released, he said.

Police weren’t investigating any of the comments as threats.

Police identified the Jeep Wrangler driver as Jenette Ward, 28, of Jefferson City, Mo. She and two back seat passengers, Kayleigh, 7, and Andi Ward, 4, were not hurt.
