Most online escort ads include sexually suggestive or explicit photographs, mainly of women in local hotels, which often help police identify a prostitute’s location by the pattern of a bedspread or curtains, said Braintree Police Chief Russell W. Jenkins. Part of his department’s enforcement efforts now include a close relationship with the managers of the six hotels in town, who eagerly contact police if they suspect prostitution activity.
Beyond fostering relationships with hotel managers, police in Brookline, where prostitution spillover from Boston has been a long-recurring issue, have made connections with several residential building managers who lend police vacant apartments to perform stings, said Detective Sergeant Thomas Ward.
