BOSTON (AP) _ Boston Police Commissioner Ed Davis says a suspect arrested in connection with two other attacks on women in South Boston this week is a ``person of interest'' in the abduction and fatal stabbing of a 24-year-old woman.

Davis says no arrests have been made in the killing of Wilbraham native Amy Lord, but said investigators are examining DNA and other evidence and are ``confident and comfortable'' they are on the right track. (Associated Press)
