Five dead, more than 40 hurt after SUV plows into marchers at Wisconsin holiday parade

An SUV plowed into a holiday parade in Waukesha, Wisconsin, Sunday, killing five people and injuring more than 40 others, police said. Videos of the incident posted on social media showed a red SUV speeding around the parade marchers and eventually hitting a group of participants.

At a news conference Sunday night, Police Chief Dan Thompson said the SUV had been located and a person of interest was in custody. 

A law enforcement official familiar with the early findings of the investigation told CBS News it appeared the suspect was fleeing another scene -- possibly a knife fight -- when he ran into the people at the parade, and the incident didn't appear to be an act of terrorism "at this time."
