DC Simon Tait and DC Eva Sharpe draw a connection between the screen name "Mercador" and the murder weapon (an ice pick of the type used to break up ice for drinks) because a web search on the terms returns a result about Leon Trotsky's assassination. This line of inquiry is later bolstered when a suspect is linked to a picture of Trotsky and to The Stranglers song "No More Heroes." Trotsky's assassin however, was named Mercader, not Mercador, and his weapon was a completely different kind of ice pick, one for mountaineering, sometimes called an ice axe.
