At the time of the attack, Inspector Joel Kaminskis was parked in an unmarked car when he said he saw multiple police cruisers fly by with their lights and sirens blaring.
“Waukesha State Patrol Dispatch advised Waukesha just had someone drive through a parade and advised the driver was shooting out the vehicle,” he wrote in an official report on the incident. Police later confirmed that the driver was not actually shooting at the time.
“Dispatch also advised this was a mass casualty incident with various levels of injuries,” he added.
Along with another officer identified only as Trooper Schlopp, he drove to the scene and discovered upon arrival he was having radio trouble.
“I immediately put on my tactical vest, grabbed my medical bag and deployed with my rifle in call ready,” he recounted.
Then he joined forces with another officer – whose name he did not know – and began treating the dozens of victims they found.
“The unknown officer and I began checking on the injured in the roadway and inside the local shops,” he said. “We assisted many people, with wide ranging injuries.”
Then he came upon the girl who told him she’d been run over and had pain in her leg and head. He drove her and an unidentified male victim to the hospital together at around 5:15 p.m.
By the time he contacted the girl’s parents, he learned that most of her family had already been rushed to the hospital – and they couldn’t find her brother. He tried to help by linking them up with Waukesha’s family reunification center.
On the way out of the hospital, he met another victim – a man whose wife suffered severe injuries in the attack and was bleeding.
He helped the husband carry her into the emergency room. As hospital staff treated the wounded mother, Kaminskis said he looked over the couple’s two young children in the parking lot until their father returned outside.
