Currently, B and 13th Street is the hottest buyers' paradise for coke and weed north of the park. So that a DOA addict around the corner would not be too surprising.
Of course not o-so-long ago you could watch live bodies get converted to dead ones. One particular example I recall was when I was sitting outside at Life Cafe on 10 and B across from the park (very early 90's) on a bright sunny Sunday afternoon around 3PM when very unceremoniously this woman put two into the head of a guy as they both stood right in the intersection of 10 and B. He went down like a rock and she was gone instantly. EMS was there rather more quickly than usual and the TNT Squad ( A Dinkins invention -tactical cops with heavy weaponry, decked out for assaults ) showed up way too late to even get the trail of the woman. And even this did not make it into the media at all -but back then the daily rodeo around the nabe provided many more such incidents than the news could find exceptional.
