Boston Police Department Commissioner William Evans

At a press conference Monday morning, Evans, who's 59, announced his rumored retirement. He thanked his family, Walsh and the entire police department.

"I'm only as good as the people I lead, and they've done a great job," he said.

“You know, it's been a great ride,” he added. “I've loved every minute. I can't say that I ever got up a day in my career where I haven't wanted to go to work, and I don't think a lot of people can say that.”

Evans will retire from BPD Saturday. He'll become BC's executive director of public safety and chief of police on Monday.

Walsh praised Evans' time on the force and said with him at the helm, Boston police have become a national leader in community policing.
