Keith Boyer spent 27 years patrolling the streets of Whittier and had become something of a legend at the Whittier Police Department.

Whittier Police Chief Jeff Piper broke down in tears recounting Boyer, whom he described as a close friend and beloved member of the department. Boyer was fatally shot Monday.

Piper said Boyer, 53, was a mentor to others in the department and had recently talked about retiring.

At the police station, he was known for his sunny, friendly disposition and willingness to lend help and offer advice, the chief said.
