Investigating any crime scene requires finesse, but in the case of Rhoda Nathan’s 1994 beating death, at least some of the detectives arriving at the Embassy Suites hotel, many who had never investigated a murder before, thought they were dealing with a heart-attack victim. As such, they say they didn’t immediately secure the scene, allowing outsiders to tromp through a room that was already teeming with all kinds of hotel-user DNA.
