Boston Police Commissioner to Step Down

Was the face of the marathon bombing investigation

Boston Police Commissioner Edward Davis, who led his department's response to the Boston Marathon bombing, says he's stepping down after seven years on the job.

Davis said Monday it's been an honor to serve the people of Boston and thanked a number of individuals, including Mayor Thomas Menino. He says Menino showed him the importance of connecting with the community.

The 57-year-old Davis was appointed Boston's top cop by Menino in 2006. He previously served as the Lowell, Mass., police superintendent.
