A resident of Harbor Avenue in Sag Harbor called police on July 31 when, just before 10 p.m., a man claiming to be with the Suffolk County Sheriff's Office knocked on his door and began asking questions about a woman named "Lisa." The man, described as "late 40s or early 50s, wearing a baseball cap and plainclothes, with a shield on a necklace around his neck," provided no identification and left when the resident said he didn't know Lisa. Officers canvassed the neighborhood but couldn't find anyone matching the description.
