While at Oberon Middle School in 2014, Beesley was able to get a bicycle for a boy with special needs but the student’s mother didn’t want him to ride his bike to school alone. That’s when Beesley decided to ride his bicycle to the boy’s house so they could ride to school together. They also rode home from school that day.

The Arvada Police Department wanted to show people how committed Beesley was to his job and students at Oberon Middle School.

In his bio on the city’s website, his motto was quoted, “Look for the good in every day.”

“We are waiting to release his identity until his family has been notified,” said Arvada Deputy Chief Ed Brady had said earlier on Monday before the department released Beesley’s name.
