LOOK: Graphic Video Reveals Moment Speeding SUV Plowed Through Christmas Parade

Our nation, as bereft with tragedy as it already was, has been saddled once again with the mourning of a senseless act…and only 50 miles from the already-tense scene in Kenosha, Wisconsin.

In the quaint Milwaukee suburb of Waukesha, a horrific act has scarred the pre-holiday landscape.

A treasured rite of the holiday season turned into a scene of bloody, deadly mayhem late Sunday afternoon as a vehicle plowed into the Waukesha Christmas Parade, killing some and leaving more than 20 people injured, authorities said.

There were some fatalities but a figure was not released as authorities sought to notify families.

Eleven adults and 12 children were ferried to local hospitals. Others were taken by friends and family. Children’s Wisconsin hospital said it had 15 patients and no fatalities.

Waukesha Mayor Shawn Reilly called the incident a “horrible and senseless act.”

The moment was captured in several pieces of graphic video, many of which were shared to social media.

While many of the details were still scarce late into the evening on Sunday, authorities have revealed that a person of interest has been taken into custody, and that an unknown number of those struck by the vehicle are deceased.
