What they didn't yet know was that a gunman, who had recently been released from police custody by a judge, had gathered several guns and fired rounds for the sole purpose of drawing a response from local law enforcement. He then waited for the officers to arrive hiding in a nearby ditch.
As Officers Hofer, Pietrowski, and Sarro arrived, they searched the park, looking for the source of the gunshots. Officer Hofer noticed movement in the ditch and headed toward it. The suspect then stood up from his hiding place and shot the officer, fatally wounding him. He also immediately shot at Officers Pietrowski and Sarro.
"I was trying to process everything," Officer Sarro said. "What just happened? Was that real? I don't hear Dave [Hofer], that's not good, so I start returning fire."
"[Sarro] came on the radio, 'Officer down, shots fired,' and you can hear him shooting a distance from him," Officer Pietrowski said.
Officer Sarro, who was just feet away from Officer Hofer, started shooting back as he fought for cover. Officer Pietrowski engaged with the suspect from 40 yards away to try to draw the gunman's attention away from Officer Sarro. They were able to fire off multiple shots, striking and killing the suspect.
