Did Marriott killer strike before?

Surveillance image from the Marriott last night shows possible killer. Via BPD.

Boston Police report detectives are looking at whether whoever murdered a woman at the Marriott in Copley Square last night held up another woman at gunpoint at the nearby Westin early on April 10.

Police add that last night's victim, a New Yorker apparently in town to sell massage services advertised on Craigslist, died after a struggle. They are withholding her name until her next of kin can be notified.
