MILWAUKEE (WKOW) -- Friday marks one year since a gunman killed five co-workers at Miller Brewery in Milwaukee.
Milwaukee police tactical officers Erin Tischer and James Sommer were some of the first officers on scene.
Both recall seeing a very chaotic scene and say the most challenging part of responding to a mass shooting there was the sheer size of the buildings they had to clear.
"There were multiple victims we saw initially right away. I think there were 8 or 10 floors we were going up and down searching every nook and cranny," said Tischer.
