“His hellos helped me get through the day,” said former Oberon Middle School Student, Jaylee Robertson. “We’re all really sad that he’s gone now. He would always just make sure we’re okay.”

Hether Florman, an Olde Town Arvada salon owner, delivered dinner to police officers working around the clock.

“There’s so much bad going on, and why people do this, I just don’t understand,” Florman said.

Those who knew Officer Beesley well say he was more than just a badge.
