BOSTON (AP) — A Boston police spokeswoman says Commissioner Edward Davis is stepping down.
Spokeswoman Cheryl Fiandaca says Davis has submitted his letter of resignation to Mayor Thomas Menino and will hold a news conference Monday to discuss his future plans.
Davis is most notable for his leadership during the response to the April 15 bombing of the Boston Marathon that killed three people and injured more than 260.
The 57-year-old Davis previously served as the Lowell, Mass., superintendent of police before coming to Boston in 2006.
Davis' departure is not unexpected. Boston is poised to have a new mayor for the first time in two decades after Menino opted not to seek another term.
A preliminary election on Tuesday will whittle a dozen candidates down to two for the Nov. 5 election.
